To help study them, biologists have devised ways of naming and classifying them according to their similarities and differences. Therefore, each species belongs to a genus, each genus belongs to a family, each family belongs to an order, etc. There are five kingdoms, which are animals, plants, fungi, prokaryotes, and protoctists, which are one-celled organisms.

A species consists of all the animals of the same type, who are able to breed and produce young of the same kind.
