Examples of decomposers include bacteria, fungi, some insects, and snails, which means they are not always microscopic. In addition to fungi, bacteria are also decomposer organisms. Decomposers are especially important in immobilizing, or retaining, nutrients in their cells, thus preventing the loss of nutrients, such as nitrogen, from the rooting zone. Examples Of Decomposers. They break down the organic matter of dead animals and plants and releases essential minerals back to the environment. In particular, make sure students understand what primary producers and primary consumers are and which organisms in their food webs fill these roles. They eat the primary consumers.When the primary consumer dies it is eaten by decomposers. Decomposers include saprophytes such as fungi and bacteria. These organisms carry out the process of decomposition, which all living organisms undergo after death. Examples of decomposer bacteria include Bacillus subtilis and Pseudomonas . 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.
