Four Types of Biodiversity
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. …
- Ecosystem Diversity. …
- Functional Diversity.
How does biodiversity relate to genetic diversity?
Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction. … Genetic Diversity is the diversity of genetic characteristics (expressed or recessive) within a species (i.e. between individuals and populations of the same species).
What are the examples of genetic diversity?

What is the meaning of genetic diversity?
Genetic Diversity refers to the range of different inherited traits within a species. … Genetic diversity is critical for a population to adapt to changing environments.
What is functional biodiversity?
Functional biodiversity refers to the set of species that contribute to ecosystem services in an agroecosystem. In other words, it is the biodiversity that is useful to farmers. It provides benefits that can be valued by the farmer through environmental management.
