Definition of Biodiversity

Biodiversity is the variety of life that is present on the planet Earth. It is generally a measure of variations that are existing at the genetic level, species level as well as in the ecosystem. The presence of moderate temperature and a high level of primary production makes the terrestrial biodiversity greater at the point of the equator. There is no even distribution of biodiversity on the Earth.

Example of Biodiversity:

Take an example of tropical rainforests which cover almost 10% of the Earth’s surface but constitute 90% of the world's species. Terrestrial biodiversity is estimated to be 25% greater than that of ocean biodiversity. The reason behind this is that biodiversity is highly dependent on certain factors like temperature, availability of nutrients, altitudes, soils, geography, etc.
