More formally, biodiversity is comprised of several levels, starting with genes, then individual species, then communities of creatures and finally … Though the species and organisms in each level may vary from each other, they too form important interactions that have bigger ripple effects on other species and organisms. 0000004863 00000 n reflects the entire range of evolutionary and ecological adaptations of species to particular environments. Biodiversity is usually plotted as taxonomic richness of a geographic area, with some reference to a temporal scale. The wild species are of considerable potential benefit to man in medicine, agriculture and industry as a natural source of drugs, food, fuel, fibre, industrial base compounds and additives. 1.

All forms of life from microbes to plants to humans contain genes. Biodiversity is an essential part of the solution to climate change. Taxonomic Diversity. Ecosystem diversity could be best understood if one studies the communities in various ecological niches within the given ecosystem. There are 3 types of biodiversity: Species biodiversity -------------- The variety of living things (e.g. Copyright. Biodiversity and its Types Biodiversity Definition “Biodiversity is the variation among living organisms from different sources including terrestrial, marine and desert ecosystems, and the ecological complexes of which they are a part.” Biodiversity is a compound word.
