This term refers to biological diversity – heterogeneity. This has two components, on the one hand diversity in the narrow sense, which is the number of species and, on the other hand, disparity, which is the number of body plans of organisms and their difference. We can speak of local biodiversity, i.e. the diversity and disparity of species occurring in a particular territory or in a certain kind of habitat, and of global diversity, i.e. diversity and disparity of all the organisms on the Earth.
