Explain what is meant by species diversity?
Species diversity. The diversity includes the whole range of organisms found on earth. The number of identified species worldwide is between 1.7 and 1.8 million. However, the estimates of total known species maybe 50 million. A large number of plant and animal species are yet to be identified. There are many more species present in the tropics. The two important measures of species diversity are: Species richness: It refers to the number of species per unit area. Species evenness: It refers to the relative abundance with which each species is represented in an area. The variety and number of individuals determine the level of diversity of an ecosystem. The Western Ghats have a greater diversity of amphibian species than the Eastern Ghats.
