An organism that creates energy from the organic matter of dead  plants or animals is called a decomposer. Most bacteria and fungi  are decomposers.

Most of them are classified as saprophytes because they live on dead or dying material and obtain energy by breaking down organic matter in dead plants and animals. Like the actinomycetes, fungi take over during the final stages of the pile when the compost has been changed to a more easily digested form.

Bacteria that feed on dead organisms are called decomposers. I will explain how it works with plants. When plants are eaten by an animal or have died there are called ammonium… compounds. Then ammonium compounds are decomposed by bacteria called decomposers and turned into nitrites.

Most compost bacteria are heterotrophic, meaning that they can use living or dead organic materials. Some are so adaptable that they can use more than a hundred different organic compounds as their source of carbon because of their ability to produce a variety of enzymes.

Chapter 1, The Decomposition Process The process of decomposition — the breakdown of raw organic materials to a finished compost — is a gradual complex process, one in which both chemical and biological processes must occur in order for organic matter to change into compost.

In these processes, bacteria, fungi, molds, protozoa, actinomycetes, and other saprophytic organisms feed upon decaying organic materials initially, while in the later stages of decomposition mites, millipedes, centipedes, springtails, beetles and earthworms further breakdown and enrich the composting materials.

What are bacteria that live on dead organic matter called? Saprophytes are a classification of bacteria that gets their nutrition from dead organic matter. These are more commonly called decomposers.

In aerobic decomposition, living organisms, which use oxygen, feed upon the organic matter. They use the nitrogen, phosphorus, some of the carbon, and other required nutrients. Much of the carbon serves as a source of energy for the organisms and is burned up and respired as carbon dioxide (C0 2).
