What happens when a herbivore is removed from a food chain?

Answer 1

If a herbivore is removed from the food chain ,the level one carnivores which would otherwise eat the herbivore,would starve to death,as they can not eat producers nor can they eat level 2 or level 3 carnivores.

ex. in a foodchain of grass-grasshopper-frog-snake ,if we remove grasshopper(herbivore),frog the level 1 carnivore,would die of starvation as it can not eat grass,nor can it eat snake.It will get in to other foodchains for survival and will disturb the regular echosystem.

Answer 2

If an organism is removed from a food chain, the organism which feeds on it would suffer. The effects however might be positive or negative. E.g leaf-caterpillar-bird-fox ( -) means food for If for instance the bird is taken out of the food chain, the foxes would starve because they would have no food to eat and would eventually die. The caterpillars however, would thrive due to the fact that it no longer has and predators so there would be more caterpillars. But since there would be more caterpillars, the leaves would suffer because there would be more caterpillars to feed on them. I hope this helps!
