Answer: Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.
Explanation: Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
- Genetic diversity is all the different genes contained in all individual
plants, animals, fungi, and microorganisms. It occurs within a species as
well as between species.
- Species diversity is all the differences within and between populations
of species, as well as between different species.
- Ecosystem diversity is all the different habitats, biological communities,
and ecological processes, as well as variation within individual ecosystems.
