The question was asked in my homework.

My question comes from Food Webs topic in chapter Ecosystems of Energy Management

Answer 1

Correct choice is (c) Because it eats producers as well as consumers

To explain I would say: Detritivores are heterotrophs that obtain their nutrition by feeding on decomposing plant and animals. Detritivores play an important role in all ecosystems by getting rid of decaying organic matter left behind by the organisms.
