In natural science, a decomposer refers to an organism that breaks down dead animals, plants, and other organic materials into simpler substances. They play a crucial role in the process of decomposition and recycling of nutrients in ecosystems. Decomposers obtain energy by breaking down complex organic matter, such as dead plants and animals, into smaller molecules that can be absorbed and utilized by other organisms. Examples of decomposers include bacteria, fungi, and certain types of insects.
