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.
