What level of classification is an order?

The seven levels of classification are: Kingdom, Phylum, Class, Order, Family, Genus, ______.

Classification Overview

Kingdom is the largest classification group encompassing all organisms.
The classification hierarchy includes seven levels: Kingdom, Phylum, Class, Order, Family, Genus, and Species.

Kingdoms

Animal Kingdom comprises multicellular organisms that move and consume food; includes humans.
Plant Kingdom consists of multicellular organisms containing chlorophyll, primarily stationary.
Fungi Kingdom represents multicellular organisms that absorb nutrients from other organisms.
Bacteria Kingdom involves single-celled organisms reproducing through cell division.
Protista Kingdom includes mostly single-celled organisms with nuclei and organelles, some having cell walls; e.g., amoebas.

Classification Levels

A class is a subdivision of a phylum; mammals exemplify this level.
Family is a division of an order; Ursidae (bears) is a typical family.
Phylum represents the largest division of the Animal Kingdom.
Order is subdivided from a class; Carnivora is an order of carnivorous mammals.
Genus is the division within a family; it forms the first part of a scientific name.
Species, the most specific classification level, distinguishes individual organisms within a genus.

Taxonomy

Taxonomy is the science dedicated to the classification of living things, organizing biological diversity.
