Dead leaves on the forest floor become new soil through the action of decomposers.

Here's how it works:

* Decomposers are organisms like bacteria and fungi that break down dead organic matter (like leaves) into simpler substances.

* They release enzymes that digest the leaves, releasing nutrients back into the soil.

* This process is called decomposition.

* Over time, the decomposed leaves, along with other organic matter, mix with the existing soil to create rich, fertile soil.

This process is essential for the health of the forest ecosystem, as it provides nutrients for new plant growth and supports a diverse range of organisms.
