It uses a hierarchy in which smaller groups are placed within larger groups with no overlap
Classification arranges living things into a series of nested groups. Every small group sits entirely inside a larger one, and no group ever belongs to two different larger groups at the same time.
Real World
Every domestic dog — from a Chihuahua to a Great Dane — sits within the species Canis lupus familiaris, within the genus Canis, within the family Canidae, within the order Carnivora, each group nesting inside the next with no organism belonging to two genera simultaneously.
Exam Focus
List the hierarchy levels in order (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species) — marks are often awarded for correct sequence, not just naming levels.
