WebBiodiversity can be thought of as a study of all the variation that exists within and between all forms of life. Biodiversity looks at the range and variety of genes, species and habitats within a particular region. It can be assessed on different scales. WebBiodiversity is a measure of the range of living organisms within a habitat. A gene pool is the range of DNA in a species. Biodiversity can be maintained by conservation, preservation and gene banks.
