Grass's Powerful Role in Ecosystems Explained #worldbuilding # #insects #evolution

追加: 2026-05-17

[00:00:00]Why? Because grass expects to be eaten.

[00:00:03]It evolved to survive grazing and trampling.

[00:00:06]Grass does not hide from herbivores.

[00:00:09]Herbivores actively seek it out.

[00:00:12]As a result, herbivores become the dominant biomass, the shapers of the landscape, the drivers of predator evolution, the primary resource for scavengers and decomposers.

[00:00:25]Why are herbivores so influential?

[00:00:28]First, they control nutrient flow.

[00:00:31]Energy flows from grass to herbivores, then to predators, followed by scavengers, and finally to decomposers.

[00:00:40]Every migration carries energy across the land.

[00:00:43]When herbivores move, nutrients move with them.

[00:00:47]Second, they decide who eats and who starves.
