Decomposition is the process by which substances are broken down into simpler forms of matter. Abiotic decomposition breaks down non-living matter. Biotic decomposition breaks down the components by living organisms. The decomposition of a dead animal, for example, occurs in two ways: the breaking down of tissues by the body’s own internal chemicals and enzymes, and the breakdown of tissues by bacteria, fungi, and scavengers such as insects and vultures. These decomposition processes release gasses.
