ecosystem

追加: 2026-05-09

[00:04:16]looks great.

[00:04:38]Looks good on the iron.

[00:05:02]Turn on this light. Look, the written words might be getting a little blurred.

[00:06:09]Why are you adjusting it in fake, sometimes it gets blurred, it happens because of the camera, it is set on auto focus, it starts happening automatically on auto focus and I zoom, why am I adjusting it and sometimes it gets blurred, son, it happens because of the camera, it is set on auto focus, I feel that it has become very clear now, I am adjusting it. It happens because of the camera, now it will be very clear.

[00:07:20]Now all the subjects are coming in studies also.

[00:07:21]I'm looking at my screen right now. Everything is absolutely clear.

[00:07:35]Amna must be hearing double voice. Now only single sound will be coming.

[00:07:42]All the audio and video is clear now brother, everyone has joined Aadin, Aman and Aadiuddin, everything must be coming very clearly.

[00:08:33]No child will face any problem. That's how it should be, I think.

[00:09:27]We are not visible to you, so the sound and the things right in front should be very clear, which is the main motive, you will be able to see the sound, now the writing on the board is very clear to everyone.

[00:10:12]If there is any blur in between then do n't worry. Things keep getting blurred.

[00:10:18]All these are machines in themselves, so they automatically go into auto adjustment.

[00:10:25]Now the voice is very clear and the thing written in front has also become very clear. So let's start the class. A very warm welcome to all the children and our chapter has started. It is our responsibility to read and understand all the concepts of NCERT line by line.

[00:10:56]And we have to look at all these concepts very carefully so that we can continue studying NCERT comfortably.

[00:11:06]Try to buy the book, it will be better for us and we can start it now. Come on, let's get started.

[00:11:34]As we have a nice line written in front of us from NCERT. The line is telling us that in Chapter 13 you have studied about the various components of the environment which include both types of components biotic and abiotic components.

[00:11:56]We get a question that brother, how many types of main components are there within the ecosystem? So two types of components work under the ecosystem. The components found in a plant are mainly called biological components. The second component found is what we call the primarily inorganic component? I know. You people know about this thing very well. The components we have serve two purposes.

[00:12:33]One component is biotic within the ecosystem and the other component found there is abiotic.

[00:12:42]We are discussing this point.

[00:12:46]This point will talk about organic and inorganic.

[00:12:52]See, when we mainly discuss about the abiotic component or talk about the biotic and abiotic components, then the first component in it is the biotic. Look, let me tell you a very small thing. The ecosystem mainly works to explain the interactions that take place between an organism and its environment.

[00:13:17]We mainly know the activities taking place between an organism and its environment by the name of ecosystem. An ecosystem is formed by two types of components. The first component among these components found is known to us as the main biological component.

[00:13:33]And the second component is called abiotic component. When we discuss about the biological component, then let me tell you that brother, the meaning of biological component is that when we are talking about life, then the biological components found in the ecosystem mainly serve three types of purposes.

[00:13:57]Look, here we will mainly tell you that the first thing that will come in the biological component is mainly the producer. The second type of organisms that come are mainly known by the name of consumers.

[00:14:14]And what about the third type of organisms that come under the name of decomposers? Will know. Look, before reading NCERT, we should know some things in reference. When we will mainly discuss about biotic and abiotic components.

[00:14:31]So to see and understand, the biological components that we have perform three types of living functions. We know one type of component found as a producer. The second component is called consumers. And the third type of components that do the work of living, what will we do by calling them mainly decomposers? Will know. You all know this very well. Ok? Do n't focus on what is written right now. Right now we have to focus only on this classification that we are doing, above this when we talk about producers here, then everyone knows that those organisms found in the ecosystem which produce food by doing the process of photosynthesis. What will we do with the names of the main producers found in them? Will know.

[00:15:27]Whom shall we call producers? Producers are said to be those organisms that produce food by carrying out the process of photosynthesis.

[00:15:38]What do we call them primarily producers? I know. We know this. The next thing we do is talk about it.

[00:15:45]What comes next is the consumer. Let me tell you about the consumer.

[00:15:50]Who is called a consumer? So, those organisms found within the ecosystem which work to obtain food from plants are mainly known as consumers. The third word that comes up when discussing decomposers is decomposition.

[00:16:09]What are called decomposers? So let us tell you that such organisms are found which work to convert complex organic substances into simple organic substances.

[00:16:21]Through these, the work of recycling of substances is done.

[00:16:29]What would we do with the organisms found in this type, primarily called decomposers? Will know. So here we discussed about organic. When we discuss about biological, then biological means those components in which life exists.

[00:16:48]What do we call these types of components found mainly biological components? Do you know there are three types of these, brother? The first component to be found is the producer.

[00:16:55]When you discuss about producer, what does producer mean?

[00:17:00]Organisms that produce food by carrying out photosynthesis in the presence of sunlight.

[00:17:08]Organisms found in this type are known as producers. The others who are in front of you are called consumers. Organisms found in such a way that they obtain food from plants.

[00:17:21]We primarily know them as consumers. The third type of organisms are called decomposers. What does decomposer mean?

[00:17:31]Decomposers are organisms that break down complex organic substances into simpler organic substances. Such organisms are known as decomposers.

[00:17:45]Now here I am going to take some examples.

[00:17:48]Who is the producer referring to? Producers are those who are involved in the production of food by carrying out the process of photosynthesis.

[00:17:54]These are the only two in nature, brother. One is plants and the other is the algae which are found mainly.

[00:18:02]They produce food by carrying out the process of photosynthesis.

[00:18:07]When we discuss about the second type of living beings, then consumers are consumers who live in three ways. You all know it. There are three types of consumers, brother. Let's take a look at it very carefully.

[00:18:22]Watch and pay attention to the matter.

[00:18:26]Come to the consumer. Who are consumers calling?

[00:18:27]Consumers There are three types of consumers. First are the primary consumers. The second one is in front of you, which is called secondary consumer and the third consumer in front of you is called tertiary consumer.

[00:18:47]Who will be called the primary consumer? So let me tell you about the primary consumer. Primary consumer means such consumers.

[00:18:57]Such consumers who obtain food from plants are known as primary consumers. For example, all the creatures that come under this are vegetarian. Let us assume that deer comes under primary consumer. It works to obtain food from plants. Take the rabbit, it is a primary consumer. Take the goat, it is a primary consumer. Take the grasshopper.

[00:19:25]is the primary consumer.

[00:19:27]When we discuss about secondary consumers, it is also clear that the meaning of secondary consumers is such consumers who consume the primary consumers as food, they are known as secondary consumers.

[00:19:41]And the third heading is tertiary consumers. Consumers found in such a way that they consume both primary and secondary consumers as food.

[00:19:50]This type of consumer is known as tertiary consumer.

[00:19:56]Like here I present a small thing before you. Let's see. Pay attention to the matter. Let's clear this up a bit when we discuss it here. It would be great if things become a little clearer in your minds.

[00:20:13]Here we mainly discussed about the consumer.

[00:20:21]Consumer, please turn off this light, son. The flash is coming very fast. So, when we discuss about the consumer, I would like to tell the consumer to make it a little clear to you and pay attention to the matter.

[00:20:44]Theme Theme Theme Brown it.

[00:20:48]Akbar Sir, make the brown and the marker yellow so that the children can see clearly. I am teaching and joking.

[00:20:55]Let's look here carefully.

[00:21:05]Who is called a consumer who gets what from plants?

[00:21:12]Work to obtain food. They are called consumers. How many types are there? Three types. Which is the first one?

[00:21:20]primary. Hey, which one is the other one? Secondary.

[00:21:24]And which is the third one? Tertiary. That's it.

[00:21:29]Oh, that's it.

[00:21:32]When you will discuss about primary consumers who will get food from the plants found mainly in trees.

[00:21:41]This type of consumer is called primary consumer. Hey brother, on whom are you trying to depend? Above the plants. They mainly work to obtain food from plants.

[00:21:57]What type of consumer found in this way will we call primary consumer? Will know. Secondary consumers are those consumers that consume primary consumers as food. Secondary consumers and tertiary consumers refer to those consumers who primarily consume both primary and secondary consumers as food.

[00:22:17]What do we call them primarily tertiary consumers? I know.

[00:22:19]Let us identify it and see how successful you are in identifying it. A small table, we are writing a small line in front of you. Please tell us your identity. Let's go here first of all I took the plant. The work of eating the plant is mainly done by a locust. The work of eating grasshoppers and locusts is done by the snakes that are found predominantly.

[00:22:45]And tell the snake to eat.

[00:22:47]Hey brother, who did the work? The peacock did the work. Let me ask you to tell me who is the primary consumer, who is the secondary consumer and who is the tertiary consumer here? Identify quickly and tell me in the comments who is primary, who is secondary and who is tertiary in this entire line? Tell me quickly by commenting at a fast speed, which are the primary ones?

[00:23:16]Which ones are secondary? Which ones are tertiary?

[00:23:19]I wait a little bit. I have given the definition. You try holding it a little.

[00:23:26]Now the board is also running absolutely clear, brother.

[00:23:31]Now it will neither blur nor seal. Wow, a comment came from a child.

[00:23:37]What type of consumer is the peacock peacock? Zeeshan, say peacock. Hey peacock will keep saying peacock brother, tell me which consumer is peacock, hey peacock which consumer is it, is it secondary, is it first, is it third, which one is it, plants cannot be primary, how did the plant become a primary consumer, my brother, here the plant is a producer, the producer plant is a producer. The plant is making food, my brother. Where will the consumer get it from?

[00:24:22]Where will he eat? Yes. The grasshopper is primary. The snake is secondary.

[00:24:28]Peacock is tertiary. Amazing. Spectacular.

[00:24:32]is a tertiary consumer. Peacock is absolutely right. The snake is secondary. Very true. Grasshopper. Hey, where is the grasshopper secondary? Swati ji, where is grasshopper secondary? Hey, consumer is the one who consumes another living being as food. He said, come let us eat you. He will be called a consumer.

[00:24:52]Which consumer is grasshopper?

[00:24:57]Yes. Peacock Tertiary Consumer.

[00:25:00]We are satisfied with what you say. Let us put our point together. Hey, I see this line. Hey, how about plant consumers?

[00:25:13]Who is the plant eating, brother? Can a plant eat someone? He says, grasshopper, come let us eat you. Oh wow man. Yes.

[00:25:23]We will call the person who is eating someone a consumer. Yes. Let's see.

[00:25:28]Here grasshopper primary snake secondary peacock tertiary how was the talk absolutely brilliant I understood the talk it is a plant your producer tell me did you understand this much did everyone understand tell me my brother what did you understand then tell me my brother oh tell me tell me if it is clear to everyone then quickly hit your thumbs let's move ahead then yes sir this thing will be clear in your mind now neither the biller will do it nor the sealer the board all of that has been adjusted yes sir so this thing has become clear in your mind now here after consumer the next language which will come to your mind yes look yes yes yes yes yes yes yes yes we ran now yes this is right brother keep on like this now come to the second topic now there is a third type of organism whose name is decomposer decomposer is talking about such organisms which work to convert the complex organic substances present in the body of dead organisms into simple organic substances.

[00:26:53]Organisms that break down complex organic substances into simpler ones are called decomposers. Please repeat the definition with me. Repeat it while sitting at home. If you repeat it slowly and calmly in your mind, you will remember it.

[00:27:14]Who is the decomposer referring to? Organisms found in such a way that work to convert complex organic substances present in the bodies of dead organisms into simple organic substances. Such organisms are known as decomposers.

[00:27:31]Let us understand this thing ourselves. Let us try to understand this a little. We will see. Correct? pay attention.

[00:27:45]Brother, everyone has to die one day. Whoever has come will go. In our language, Urdu, it is said that Nafs Kulli Jalikal Maut. He who has enjoyed life will also enjoy death. If you taste it, you will die. No one is going to be spared.

[00:28:01]Come on, kill them. A plant died. The grasshopper died. The snake died. The peacock died. Now there are many substances inside his dead body.

[00:28:19]Whatever you have eaten throughout your life remains inside your body.

[00:28:21]Carbohydrates, proteins, various types of substances are the main substances present in the body.

[00:28:30]Now when they die, what will be done to basically decompose all the complex organic substances present within their dead body? The work will be done.

[00:28:46]Like let me tell you one thing here. Let's move a little further. Come to the next thing. A little further. What we have a discussion about here is decomposers.

[00:29:05]Who are the decomposers calling decomposers? Organisms found in such a way that they convert the complex organic substances present in the bodies of dead organisms into simple organic substances. Such organisms are known as decomposers. All the dying plants died. Primary consumers died, secondary died, tertiary died. When they die, the substances present in their dead bodies will be decomposed by the decomposers present in them and the complex organic substances present in their bodies will be converted into simple organic substances.

[00:29:56]See and understand how he is saying this. Let's say carbohydrates are present in the body of an organism. Glucose When glucose is broken down, it forms two things. One is carbon dioxide and the other is the water found there. It has been decomposed. It has been decomposed.

[00:30:21]What was the complex organic matter? Glucose.

[00:30:24]What is simple organic matter? Carbon dioxide and water. became. Come brother.

[00:30:30]If there is protein inside the body of the organism, the protein will be converted into amino acids and the amino acids will be converted into ammonia. Ammonia will be released into the atmosphere. It's done brother. This was also the most common complex organic substance.

[00:30:55]converted into simple organic matter and released into the atmosphere.

[00:30:59]These three types of organisms found in the ecosystem, we will mainly call them biological.

[00:31:08]What will you say? Organic.

[00:31:10]Now the question arises that what should we call inorganic, sir? In which there is no life. Abiotic factors mean factors found in which there is no life. But very essential for the life of the organism.

[00:31:25]Work cannot be done without them. You tell us, can plants make food by doing photosynthesis without carbon dioxide? Can't make it. Can plants make food by photosynthesis without absorbing water? Can't make it. But tell me one thing, is there life in carbon dioxide? Not there. There is no life in water. There is no life in them.

[00:31:53]But they are very essential for the life of the organism. The factors found in this type of major factors are known as abiotic factors.

[00:32:06]These are known as abiotic factors.

[00:32:08]Ok? Let us move on to the next lines of NCERT. Let's hit back a little. Let's make the story a little better.

[00:32:15]I make its background brown. It will be done well. Look here. We will not blur this anymore.

[00:32:25]Now let's focus a little bit. The camera moved forward a little bit. Very true. It must be looking good now. It is written that in Chapter 13 you studied about the various components of the environment.

[00:32:42]Which includes both biotic and abiotic components.

[00:32:45]You have studied how biotic and abiotic components individually affect each other and the environment around them.

[00:32:55]Let us now look at these components in a more integrated manner and understand how energy flow takes place within these components of the ecosystem.

[00:33:09]Here we are talking about transfer of energy.

[00:33:12]Stop, pause and look at this concept easily. I am returning. Come back brother, I have returned the crooked gilli.

[00:33:23]Look here, when you understand this thing from here, you will understand. Let's see, tell me one thing.

[00:33:37]When plants perform the process of photosynthesis, they will make food.

[00:33:43]What will you make? Meal. And when it completes the work of preparing the food, then after preparing the food, some of the energy of the same food will reach the locust from the plant. That is, when the locust consumes the plant as food, some of the plant's energy will reach the locust. If the snake eats this locust, then the energy of the locust will reach the snake in the form of food i.e. in the form of edible energy.

[00:34:20]When the peacock eats this snake, some energy from the food will reach the peacock through the snake.

[00:34:33]You will ask us a question here, Sir, I am repeating one word again and again, energy of food, energy of food, energy of food, so I will also say to you, you will ask me Sir, what is the energy of food, then I will say that energy of food means that energy which is found in the form of food, that energy which works to come from one living being to another living being, that energy which works to come from one living being to another living being in the form of food. The energy obtained in this way is known as food energy.

[00:35:14]NCERT is saying that we have to know why one organism is eating another organism? It's a simple matter. One organism eats another organism so that it can mainly obtain energy from the food.

[00:35:30]I will ask you one thing. Tell me why do you eat food? It's a simple matter.

[00:35:35]Man says the simple answer is to survive.

[00:35:38]Nor will we tell you that you eat food so that you can work to get energy because our body needs energy to function. So focus on this line of NCERT. NCERT says that when biotic and abiotic factors interact with each other or biotic and abiotic factors interact with each other, then energy is transferred between them.

[00:36:12]How is energy transferred in an ecosystem? How does the transfer of energy take place within the ecosystem? NCERT is telling us a little bit about this to focus and understand how energy is transferred. Come let's see.

[00:36:38]Hey, take it and see. Hey, they have reached within reach.

[00:36:43]This is even more touching, yes, we were not here. We were here we yes.

[00:36:55]Where did you come from? Ok. If it drips, it's good. Let's zoom in.

[00:37:04]This should be visible. Yes sir. It is written to jointly observe and understand how energy flow takes place within these components in the ecosystem.

[00:37:19]A physical structure develops as a result of the interactions between biotic and abiotic components.

[00:37:22]Exactly what characterizes each type of ecosystem. That is to say, when the biological and non-biological components found there interact with each other, they work to create a physical structure.

[00:37:37]You will remember to ask what type of structure develops when biotic and abiotic factors interact with each other? So your answer will be that brother, this structure that will be developed will be a physical structure.

[00:37:54]Who will it be son? The physical structure will serve as a residence.

[00:37:56]This has to be taken care of.

[00:37:59]Come to the next thing. Which is a characteristic of every ecosystem.

[00:38:05]Talking about the characteristics of ecosystem, what are the characteristics of ecosystem? So the speciality of the ecosystem is that when biotic and abiotic factors interact with each other, then this interaction between them will work to create a physical structure and this physical structure formed works to tell the characteristics of the ecosystem.

[00:38:30]Identifying and counting the plant and animal species of an ecosystem reveals its species composition. The vertical distribution of different species at different levels is known as stratification. Look, underline this definition like this. Looking at the underlines asks us to remember a particular line.

[00:38:54]When you are told that the vertical distribution of different species at different levels is called stratification.

[00:39:02]Look brother, you are being asked for the definition, please tell me what is called level configuration? So brother, the definition of stratification is that the vertical distribution of different species at different types of levels is known as stratification. That is, what do many different species do when arranged on top of each other? Reason. Let us understand this thing. Let's see here. Open up Sim Sim, it has opened Sim Sim. Back it up.

[00:39:36]Yes sir. Come home to this one.

[00:39:39]Click here and let us show you a pyramid. Pyramid and then you will understand.

[00:39:53]We are explaining the level configuration to you.

[00:39:55]Which configuration? Level configuration.

[00:39:59]A brother level configuration. Come on, come on, come on.

[00:40:03]White board.

[00:40:06]This is needed. I want this, this.

[00:40:18]Look, the magician's magic has come to the fore. This is the level configuration. Which configuration is it? Level configuration. Level means a configuration of levels in a dominant form.

[00:40:30]arranged one above the other. The energy that first came to us in a major form was absorbed primarily by plants. Plants performed the process of photosynthesis here.

[00:40:44]When the plant performed the process of photosynthesis here.

[00:40:49]This plant will photosynthesize. This plant will photosynthesize here. And by carrying out the process of photosynthesis, it will produce food here.

[00:40:59]What percentage did it make? 100% of our food is made by plants. When this plant is eaten by a locust, then who is present on the plant, brother? Grasshopper. That means to whom did the energy of the plant go?

[00:41:14]Near the grasshopper. Did the grasshopper primarily eat? The frog. So where did the energy of the locust go? In the frog. The snake ate the frog. So tell me, to whom did the energy reach? She managed to reach the snake.

[00:41:27]You will say Sir, please try to tell us one thing, this is level configuration. I would say yes, this is a level configuration. What is it mainly called in English as Tropic Level? I know.

[00:41:45]Yes, I am coming to the same thing, what is level configuration?

[00:41:49]Remember that the transfer of energy in every living being happens mainly in a step by step manner. First of all, the plant gets energy. Then the herbivorous animal started eating the plant. Herbivorous animals means primary consumers. The secondary consumer eats the primary consumer. The tertiary did the work of eating the secondary.

[00:42:11]Stratification means that each organism found in the plant arranges itself on top of the other on the basis of the energy it receives from each other. This means that the energy of plants is transferred to herbivorous organisms and the energy from herbivorous organisms is transferred to other carnivorous organisms.

[00:42:31]Or should I say that the energy of the plant mainly works to reach the consumer from the primary consumer, from the primary consumer to the secondary consumer, from the secondary consumer to the tertiary consumer.

[00:42:42]This order of energy that is found, the configuration in which it is found, what will we call that configuration as level configuration or tropic level? Will know.

[00:42:53]Every living being is arranged in this manner. The entire ecosystem functions in a similar manner.

[00:43:01]Every living organism in our ecosystem is connected in such a way that first the energy is obtained by the plant, then after the plant, by the herbivorous creatures, after the herbivorous creatures, then by the other carnivorous creatures.

[00:43:13]And this level of energy, what do we mainly call it by the name of level configuration? I know.

[00:43:22]Tell me brother, is this matter clear?

[00:43:25]Tell me brother, if there is any clear problem under this then ask. This level configuration is in front of you. If it is clear then give a good thumb impression. Then move ahead.

[00:43:47]Why is there so much silence, brother?

[00:43:49]Your level setting is cleared.

[00:43:53]Stratification means that each organism is present in a layer above the other. They are present one above the other and transfer of energy takes place from herbivorous organisms to lower level organisms and then to higher level organisms.

[00:44:05]We will call this type of configuration a level configuration. Brother, tell me who is this Farzana Bano, son. Did Farzana ji get it cleared?

[00:44:24]You are Farzana ji.

[00:44:29]Yes yes, so now this thing is clear in my mind.

[00:44:33]This is a very good thing for us. It is a very happy moment for us that at least this is clear in your mind.

[00:44:40]Let me first make him disappear from here. Now let me make him disappear from here first. Then after that I have to open the page again because the whole story has changed. Oh my God, come on, let's be clear. Yes, now open the page again.

[00:45:01]Yes sir. Where did our page go? Come to this home.

[00:45:04]Then come here to the books.

[00:45:08]Our bio will come back after we get back from the books.

[00:45:12]It remains a bit scheduled. Have to do it. There is also such an updated board now. But still many things have to be done manually.

[00:45:22]Honorable, this is the second page. So pick this up. Copy it clearly.

[00:45:35]It got copied. Now select it. Make it a little bigger and place it here in front of the child. This is what happened sir, things in the mind. Come.

[00:45:50]Yes sir.

[00:45:52]Now this is done. It is called level configuration.

[00:45:57]Example: Trees are the most important vertical level in a forest.

[00:46:00]Shrubs form the secondary layer and herbs form the tertiary layer or herbs and grasses form the lower layer.

[00:46:08]Ok?

[00:46:10]He explained this arrangement on the basis of plants that any living being works in this manner. The main tree found in our forest will perform the maximum amount of photosynthesis. It will create the most energy.

[00:46:28]Then after that shrubs will work to make then herbs or grasses.

[00:46:32]All the components in an ecosystem appear to function as a unit when you look at the following aspects.

[00:46:38]Productivity: We have told you that productivity means the activity in which mainly the work of producing food is done, we will know it by the name of productivity.

[00:46:48]Next is decomposition. We have also told you what the creatures found in that activity do? They work to convert the complex organic substances present in the bodies of dead organisms into simple organic substances.

[00:47:00]And thirdly there is flow of energy. The flow of energy means that energy is constantly being transferred from one organism to another in the form of food. And the fourth is the nutritional cycle. Nutrition cycle means that when our decomposers convert complex organic substances into simple organic substances, then the energy that is mainly there reaches there. From one organism to another.

[00:47:27]When good complex organic matter gets destroyed or breaks down, then whatever nutrients are found in it, whatever nutrients are there, whatever nutrients are there, they are mainly mixed together again in nature or in the soil.

[00:47:41]These are known as nutrient cycles.

[00:47:43]Now let's move on to the next thing. Yes.

[00:47:48]Look, to understand the properties of an aquatic ecosystem, let us take the example of a small pond.

[00:47:54]This is a reasonable, self-contained and relatively simple example. Which helps us understand the complex interactions here in an aquatic ecosystem.

[00:48:03]You are a little bit worried that the lines above are not that important. You look from below. A pond is a water body with shallow water. Made a pond. The pond will be an ecosystem in itself. Yes, it will definitely happen. Each pond will have all its own factors. There will be biotic factors as well as abiotic factors that will play a major role in survival. So from here on, we're just going to hold the pond ecosystem a little bit because the class will get a little longer and then the kids won't be looking as much to save their net.

[00:48:32]So tomorrow I will have a discussion and the discussion will be about the ecosystem of the pond.

[00:48:39]We will study the ecosystem of the pond in detail. Let me reveal a little about today's topic. Let me tell you his question. So let me tell you the reason behind it. So let me tell you the reason behind it. Revision makes things clear. Look, now you will see only me.

[00:48:59]Nothing will be visible in front or behind. Let's see.

[00:49:01]Vya understands it well. What topics did we discuss today? First of all we read how many types of factors are found in the ecosystem?

[00:49:09]So there are two types of components of the ecosystem or two types of its factors, components. The first is your primarily biological factor. We know about biological factors. The factors found in which life exists. Such factors are known as biotic factors. There are three types of biotic factors which we know as producers, consumers and decomposers.

[00:49:30]Who are called producers? So, such organisms which produce food by carrying out the process of photosynthesis are called producers. For example, blue green algae and mainly trees and plants will come into play.

[00:49:42]Second comes the consumer.

[00:49:45]Such organisms which depend primarily on plants for food or depend on producers are known as consumers. There are three types of consumers which are called primary consumers, secondary consumers and tertiary consumers.

[00:50:01]Who are called primary consumers? Organisms that obtain food from plants are called primary consumers.

[00:50:09]Who will be called secondary consumers? Those who consume primary consumers as food will be called secondary consumers.

[00:50:16]Who will be called tertiary consumers? Which will serve as food for both primary and secondary consumers.

[00:50:21]What would we call them as tertiary consumers?

[00:50:23]Will know. After this comes what are called decomposers? So such organisms are found which work to convert the complex organic substances present in the bodies of dead organisms into simple organic substances. Such organisms are known as decomposers.

[00:50:36]What type of process is an ecosystem? So all the activities taking place in the ecosystem come under the physical process.

[00:50:43]Under whom?

[00:50:45]What does it mean to come under physical process? Work.

[00:50:47]We have read this mainly in this.

[00:50:50]Apart from this, from where does the transfer of energy take place among the organisms found in the ecosystem? So remember that the transfer of energy always happens from higher level to lower level.

[00:51:04]Plants have the most energy. Then after that the energy goes to the primary consumer, then to the secondary consumer, then to the third consumer, then this also comes into play, sir, you should also note this down and note down in what form the energy is being transferred, so remember the energy of the ecosystem gets transferred in the form of food or in the form of food energy.

[00:51:25]What is the energy of food? So, food energy is said to be such a found energy which is passed from one organism to another in the form of food.

[00:51:34]This type of energy is known as food energy.

[00:51:39]Now here our topic for tomorrow is about the ecosystem of the pond, we will discuss that pond is a type of ecosystem. If the pond is an ecosystem then it will have biological factors as well as non-biological factors.

[00:51:54]So this was a short type explanation of ours in front of you and if you reveal and watch this video again and again, you will watch it continuously. If you have any doubt, the comment box is open for you. You can ask questions about it. I watch and also answer. Let's join you guys.

[00:52:13]Thank you very much. Many thanks to all of you. Thank you. See you tomorrow at 7:00 pm. After everything goes well. May everything be great. Stay cool. Keep reading the bio and keep learning. Let's meet again in front of NCERT.

[00:52:25]Thanks for now. We will meet again tomorrow at 7:00 pm.

[00:52:27]Thank you son. He speaks at rocket speed.
