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 (like plants) take in non - living matter (e.g., carbon dioxide, water) and convert it into living matter (organic compounds) through photosynthesis. Consumers (herbivores, carnivores) eat the producers or other consumers, using the matter for growth, repair, and energy. When organisms die, decomposers break down their bodies, returning the matter to the non - living part of the ecosystem (e.g., nutrients in the soil). This matter can then be taken up by producers again. So, matter cycles from living to non - living and back to living again. The second statement “Matter stays in the nonliving part of the ecosystem” is incorrect because in a food chain, matter is constantly moving between living and non - living components.

Answer:

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