The branch of biology that names and classifies species into a hierarchy of broader groups is called?

• A. Ecology
• B. Taxonomy
• C. Genetics
• D. Anatomy

Answer: (B)

Taxonomy is the science that names and classifies organisms, placing them into a nested hierarchy such as species, genus, family, order, class, phylum, kingdom, and domain. This system lets us organize life and show how closely related different organisms are, often using a unique two-part name for each species (binomial nomenclature). The other fields focus on different questions: ecology studies how organisms interact with each other and their environment, genetics examines heredity and gene variation, and anatomy looks at the structure of organisms. So taxonomy specifically addresses naming and ordering species into broader groups, which is why it’s the correct choice.
