Levels of Classification

Kingdom is the broadest level of biological classification.
Class follows phylum in the hierarchical classification system.
Family is the classification level between order and genus.
Taxonomy is the branch of science that classifies organisms, including naming and categorization.
Species represents the most specific category in classification.
Order comes after class in the classification hierarchy.
Classification organizes organisms into categories based on shared characteristics.
Genus is the classification level that follows family.

Classification Systems

Binomial nomenclature uses a two-word format for organism naming: genus name followed by species name.
Phylum is the classification level that comes after kingdom.

Biological Kingdoms

Archaea includes ancient bacteria that can survive in extreme environments.
Plantae is the kingdom comprising multicellular plants.
Animalia consists of complex multicellular organisms, primarily heterotrophic (consume their own food).
Fungi are complex organisms that absorb nutrients from their environment.
Bacteria refers to kingdoms containing simple unicellular organisms.
Protista includes unicellular organisms that are more complex than bacteria and archaea.

Test your knowledge on the levels of biological classification, from kingdom down to species. This quiz covers important concepts such as taxonomy, binomial nomenclature, and the various biological kingdoms. Challenge yourself to see how well you understand the organization of living organisms.
