Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world. Using morphological, behavioral, genetic and biochemical observations, taxonomists identify, describe and arrange species into classifications, including those that are new to science. Using behavioral, morphological, genetic and biochemical observations, taxonomists identify and arrange the species into classifications, including those that are new to science. Taxonomy identifies and mentions the components of biological diversity providing basic knowledge grounded the management and implementation of the Convention on Biological Diversity. The taxonomic knowledge is far from complete. In the past 250 years of research, taxonomists have named about 1.78 million species of animals, plants and micro-organisms, yet the total number of species is unknown and probably between 5 and 30 million.
