A taxonomic group is a way of classifying living organisms. It is divided into three levels: GENUS, phylum, and SPECIES. A GENUS is the most general level and is made up of closely related SPECIES. A phylum is a more specific level and is made up of related genera. Finally, a SPECIES is the most specific level and is made up of individuals that are able to interbreed. By using these three levels, scientists can accurately classify and identify living organisms.
