Four major components of biodiversity are:
1. Genetic diversity - refers to the genetic variation that occurs among members of the same species.
2. Species diversity - (taxonomic diversity) refers to the variety of species or other taxonomic groups in an ecosystem
3. Ecosystem diversity - refers to the variety of biological communities found on earth. With ecosystem diversity, its two levels are generally considered, which are communities and ecosystems.
4. Functional diversity - refers to the variety of biological processes, function or characteristics of a particular ecosystem.
