Question

which component of the ecosystem is responsible for returning nutrients from decaying matter back to the food chain?
detritivores
erbivores
the sun
rocks

Explanation:

Detritivores break down decaying matter. This process releases nutrients back into the ecosystem, which can then be used by producers (like plants) in the food chain. Herbivores eat plants. The sun is a source of energy for producers (via photosynthesis). Rocks are non - living and do not directly return nutrients from decaying matter to the food chain.

Answer:

A. detritivores
