Answer: a. to decompose dead animals
Explanation:
Detritivores are the hetrotrophic organisms which feed upon detritus (dead and decaying plant and animal matter). These detritivores break down the biological dead matter into simple molecules which are readily consumed by the small microorganisms present in the soil. Detritivores are essential for the ecosystem as they return important materials such as carbon and other essential elements back to the environment after decomposing the dead matter. Example of common detritivores includes earthworms.
On the basis of the above explanation, the role of a detritivore is a. to decompose dead animals.
