Biotic Community


A distinct ecological community of plants and animals living together in a particular climate is called a Biome. According to Clements and Shelford, a complex of several communities in any area, represented by an assemblage of different kinds of plants, animals etc., sharing a common climate, is called a biome. Thus, a biome is a bigger unit than community and constitutes the great regions of the world distinguished on an ecological basis.
