What does taxonomy do? What are the largest groups of living organisms that taxonomy distinguishes? how are these groups different?

Taxonomy deals with the ordering of species of different organisms, combining them into larger taxa (groups) on the basis of kinship or differences (the lowest taxon is a species). This makes learning biology more convenient.

The largest link in the classification is the kingdom. In total, all organisms are usually divided into 4 separate kingdoms, one of which is bacteria and archaea, from which three other kingdoms differ in cell structure: fungi, plants and animals, which differ in nutritional methods.
