An ecosystem is made up of biotic and abiotic components which include plants, animals and the environment in which they are found. The living or biotic components are made up of producers, consumers and decomposers. Some of the non-living or abiotic components include sunlight, temperature, water and soil.

Producers are any plants or animals that create their own food like flowers and bacteria. Consumers are animals that feed on producers or other consumers. The consumers can include fish, bears and birds. Decomposers feed on the dead material in an ecosystem, like dead leaves or animal remains. This decomposition is normally carried out by bacteria and fungi. All of these biotic elements are influenced and dependent on the abiotic components in an ecosystem.
