Biodiversity
can be described as the sum total of all plants and animals found in a
particular area. It is basically a measure of all variations found at the
genetic, species, and ecosystem level. It is mainly influenced by the environmental,
geographical, climatic and topographical conditions of an area. Only the animals
that can adapt to a particular environment can live there. For example, freshwater
fish rohu cannot survive in marine water bodies. Because of this, the fishes
that survive on rohu can also not survive in marine habitats. Hence, the environmental
conditions of an area govern the nature of its biodiversity and result in different
places having different forms of biodiversity.
