Consider the model of the food chain. Imagine there is a herbicide poison spill and all the grass is killed. How will this influence the food chain model?
Animals that depend on this grass will either starve, or go elsewhere for food. This means that the carnivores that prey on those grass eating animals will also go hungry. This will severely disrupt the ecosystem.
it affects it because the organisms that eat grass are not gonna be able to eat and they are gonna die then the rest of the organisms are not gonna have nothing to eat
