What are the two levels of biodiversity?
Two levels of biodiversity are: (i) Species diversity: It is the diversity at species level. Eg., amphibian species are found more in the Western Ghats as compared to the Eastern Ghats. (ii) Genetic diversity: A single species shows high diversity at the genetic level over its distributional range.
