Question

what happens in a food chain?
matter cycles from living to nonliving and back to living again.
matter stays in the nonliving part of the ecosystem.

Explanation:

In a food chain, matter is cycled. Producers (living) take in nonliving matter (e.g., carbon dioxide, water) and convert it into organic matter. Consumers (living) eat producers or other consumers. When organisms die (become nonliving), decomposers break them down, returning matter to the nonliving part of the ecosystem. This matter can then be reused by producers again, showing the cycle of matter from living to nonliving and back to living.

Answer:

Matter cycles from living to nonliving and back to living again.
