The four types of biodiversity are as follows:
- Species diversity: Every ecosystem contains a unique collection of species, all interacting with each other. Some ecosystems may have many more species than another.
- Genetic diversity: Genetic diversity describes how closely related the members of one species are in a given ecosystem.
- Ecosystem diversity: A region may have several ecosystems, or it may have one. Wide expanses of oceans or deserts would be examples of regions with low ecological diversity.
- Functional diversity: The way species behave, obtain food and use the natural resources of an ecosystem is known as functional diversity.
