Hierarchy of Classification
Hierarchy of classification is the ordered arrangement of taxonomic categories from broad groups to specific groups: kingdom, phylum, class, order, family, genus, and species.
Practice This ConceptMain explanation
Teacher explanation
In the hierarchy, kingdom is the broadest category and species is the most specific category. As we move down the hierarchy, organisms share more features. This system helps in placing an organism step by step and understanding how closely it is related to other organisms.
Example
For humans, Animalia is the kingdom, Chordata is the phylum, Mammalia is the class, Homo is the genus, and Homo sapiens is the species.
Simple analogy
King Philip Came Over For Good Soup: Kingdom, Phylum, Class, Order, Family, Genus, Species.
Common confusion
Students often reverse the order and write species first as the broadest category.
Exam tip
Remember the order and mention that similarity increases as we move from kingdom towards species.
