How do organisms affect the environment

Nature consists of both the organism and the environment. The relationship between them are intertwined. Organisms are mainly divided into three

a) The producers

b) The consumers

c) Decomposers

These three organisms are interlinked with each other. Without them there is no existence of the environment. The producers produce the food, the consumers consume them and the decomposers decompose and release it in the form of energy. In each cycle energy is released and absorbed. The balance in the environment is maintained by the food pyramid.
