Biodiversity is the general term used to describe the variety in the living world. It refers to the number and variety of living organisms in a particular area and has three components: Species Diversity refers to the number of different species and the number of individuals of each species within any one community. Genetic Diversity refers to the variety of genes possessed by the individuals that make up any one species. Ecosystem Diversity refers to the rage of different habitats within a particular area. One measure of biodiversity is species diversity. It has two components: The number of different species in a given area. The proportion of the community that is made up of an individual species. Measuring Species Diversity: One way of measuring species diversity is to use an index that is calculated as follows: Where:‘d’= species diversity index, N = total number of organisms of all species, ‘n’ = total number of organisms of each species, Sigma = the sum of. The higher the value of d the higher the species diversity. So in this case Habitat X has a higher level of species diversity, although the total number of individuals
