Taxonomy

Taxonomy is the scientific classification or scientific system of classifying biological organisms (anything living), based on a living thing's features, structure, and (rarely) its behaviors, including plants (kingdom Plantae) and fungi (kingdom Fungi). In taxonomy, there are multiple taxon ranks before you get to a species (see both systems below). Unranked groups can appear anywhere above a kingdom. A clade is a group of organisms which is thought to have come from a particular organism. There are different ranks in zoology and botany (scientists who study water-related lifeforms also use the zoology rank system).
