What is the difference between a kingdom and domain?
A domain is a taxonomic category above the kingdom level. The three domains are: Bacteria, Archaea, and Eukarya, which are the major categories of life. Essentially, domains are superkingdoms. A kingdom is a taxonomic group that contains one or more phyla.

Humans can move on their own and are placed in the animal kingdom. Further, humans belong to the animal phylum known as chordates because we have a backbone. The human animal has hair and milk glands, so we are placed in the class of mammals. Within the mammal class, humans are placed in the primate order.

Living things are divided into five kingdoms: animal, plant, fungi, protist and monera.
What is basic taxonomy?
The smallest taxon or the basic unit of taxonomy is the species. Species in biology is a taxonomic rank and the fundamental unit of classification, as well as, the unit of biodiversity. The related species sharing structural resemblance with each other, constitute a genus.
Characterization, identification, and classification are the processes of taxonomy. Organisms are classified into similar categories namely kingdom, phylum, class, order, family, genus and species.
What is an example of a taxonomy?
An example of taxonomy is the way living beings are divided up into Kingdom, Phylum, Class, Order, Family, Genus, Species. An example of taxonomy is the Dewey Decimal system – the way libraries classify non-fiction books by division and subdivisions.
