A decomposer is a living being that breaks down all types of waste, fecal matter and all organic substances deriving from a living being. The decomposer is an indispensable element in the recycling of organic materials and what they contain, such as toxins, nutrients, and minerals. Decomposers may be insects, crustaceans, bacteria, or fungi. They are found in all ecosystems, including within an organism. Decomposers can be used to create compost or to produce antibiotics.
