Help with one Biology question? Cant find it in the book!?

Hey everyone-

Ive been looking for this bio answer in the book, and cant find it.

Can you pleaseeeeeee help me?(:

In an ecosystem with four levels—producers, primary consumers, and two higher-level consumers—describe where the decomposers operate within the context of these trophic levels. Provide at least two examples.

Thank you so so much in advance(:<3


Decomposers break down dead plant and animal material and wastes and release it again as energy and nutrients into the ecosystem for recycling. Decomposers, such as bacteria and fungi (mushrooms), feed on waste and dead matter, converting it into inorganic chemicals that can be recycled as mineral nutrients for plants to use again.

They would be found in the higher level consumers because they do not fall into the category of producers (aka plants) or primary consumers (aka animals).
