What is ecological recycling?

Back

Ecological recycling is the process of movement and exchange of living and nonliving matter back into the production of living matter, ensuring that nutrients are reused in the ecosystem.

What happens when plants decompose?

Back

When plants decompose, they break down into organic matter, returning nutrients to the soil and making them available for other organisms.

How does energy flow in an ecosystem?

Back

Energy flows in an ecosystem from producers to consumers and then to decomposers, following the path of the food chain or food web.
