Decomposer Insects

In any natural or semi-natural habitat, three types of organisms exist: producers, consumers and decomposers. Good functioning of the ecosystem will depend on their suitable action and interaction. Organisms capable of catching energy and synthesizing organic matter from inorganic compounds constitute the producers. Though chemosynthetic bacteria exist, most producers are plants. Green plants use solar energy and fix CO₂, producing organic compounds rich in energy. Most of this accumulated energy will get used in the ecosystem by respiratory processes and other vital functions, whereas some organisms of the community such as the consumers and decomposers will use the energy accumulated by other organisms.

The consumers are heterotrophic organisms that obtain food from producers or from other consumers, with the possibility of several levels of complexity inside an ecosystem. Primary consumers feed directly on the producers. Secondary consumers feed on primary consumers, etc. Finally,...
