Complete PowerPoint presentation for a 2 hour lesson on biodiversity within communities for AQA A Level Biology. Includes calculating the index of diversity, impact of agriculture on biodiversity and conservation techniques. New content slides and accompanying activities in the ‘learning loop’ format. Covers specification points: Biodiversity can relate to a range of habitats, from a small local habitat to the Earth. Species richness is a measure of the number of different species in a community. An index of diversity describes the relationship between the number of species in a community and the number of individuals in each species. Calculation of an index of diversity (d) from the formula d = N (N − 1) /n (n − 1) where N = total number of organisms of all species and n = total number of organisms of each species. Farming techniques reduce biodiversity. The balance between conservation and farming.
