The number of different species and the number of individuals of each species within any one community 3 of 9 What is genetic diversity? The variety of genes possesed by the individuals that make up any one species 4 of 9 What is ecosystem diversity? The range of different habitats within a particular area 5 of 9 What are the 2 components of species diversity (a measurement of biodiversity)? The number of different species in a given area and the proportion of the community that is made up of an individual species 6 of 9 How is diversity measured? d = N(N-1)/sum of n(n-1) with d=species diversity index, N=total no. of organisms in all species, n=total no. of organisms in each species 7 of 9 What does it mean as d increases? The greater the species diversity 8 of 9 In extreme environments, what is likely to happen to species diversity? Species diversity is normally low 9 of 9
