What is it called when living things get their food by breaking down dead matter into simpler chemicals?

The process by which living things get their food by breaking down dead matter into simpler chemicals is called decomposition. Decomposition is a natural process that occurs in all ecosystems. It is carried out by a variety of organisms, including bacteria, fungi, and some animals, such as worms and insects.

Decomposition begins when a living thing dies. The body of the dead organism is broken down by decomposers, which release nutrients back into the environment. These nutrients can then be used by other living things, such as plants, which use them to grow and produce food.

Decomposition is an important process because it helps to recycle nutrients in the environment. It also helps to remove dead organisms from the environment, which can help to prevent the spread of disease.
