In the biological sciences, the term (also "biological diversity" or "diversity of life") is a measure of the abundance of different life in a particular landscape or geographically limited area. This can refer to both the genetic diversity within a population and the degree of species richness in a specific location (habitat, region).
The biodiversity of a region comprises four levels of diversity. These are genetic diversity within a species, species diversity in an ecosystem, ecosystem diversity and functional biodiversity. In a broader sense, this refers to the entire wealth of species on earth. The existence of a large number of different plant and animal organisms is a prerequisite for a stable ecosystem.
