An organism that feeds on the wastes or remains of living things is called a decomposer.

Here are some examples of decomposers:

* Bacteria: They break down dead plants and animals, as well as waste products, releasing nutrients back into the soil.

* Fungi: Like mushrooms and molds, they break down organic matter, such as dead trees, leaves, and fruits.

* Earthworms: They consume decaying organic matter and help to aerate the soil.

* Insects: Some insects, like dung beetles, feed on animal dung and help break it down.

Decomposers play a vital role in ecosystems by recycling nutrients and keeping the environment clean.
