The organisms that break down material into nutrients for food producers are called decomposers.

Here's why:

* Food producers (like plants) make their own food through photosynthesis.

* Decomposers break down dead organisms and waste, releasing nutrients back into the environment.

* These released nutrients are then used by food producers to grow and thrive.

Examples of decomposers include:

* Bacteria

* Fungi

* Earthworms

* Insects

They play a crucial role in the ecosystem by recycling nutrients and maintaining a healthy balance.
