What happen to the rest of the trophic levels if one of them was wiped out?

Either extinction of several species or over population For instance if the trophic level of grasses and small plants died out, then there would be exinction of all species that rely on that source (soley or in majority) as food. If an upper trophic level such as large carnivors died out then you would see an over population of the animals that the large carnivor ate as a majority of its diet.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
