Which component of the ecosystem is responsible for returning nutrients back to the food chain? A. herbivores
B. rocks
C. detritivores
D. the sun

The answer should be C) detritivores

Explanation:

Decomposers (fungi, bacteria, invertebrates such as worms and insects) have the ability to break down dead organisms into smaller particles and create new compounds. We use decomposers to restore the natural nutrient cycle through controlled composting. Hope this helped and it was correct :)
