An ecosystem is a structural and functional unit of ecology where the living organisms come in to interact with each other and the surrounding environment.

Structure of the Ecosystem:

The structure of an ecosystem is distinguished by the organization of both biotic and abiotic components. This involves the distribution of energy in our environment. It also comprises the climatic conditions prevailing in that particular environment.
