Which scientific discipline classifies organisms into a hierarchical system from kingdoms to species?

• A. Taxonomy
• B. Ecology
• C. Ethology
• D. Physiology

Answer: (A)

Taxonomy is the science that classifies living things into a hierarchical system—kingdom, phylum, class, order, family, genus, species. This framework provides a consistent way to name organisms (often using binomial nomenclature) and to organize the vast diversity of life so scientists can see relationships and communicate clearly across languages and regions. While other disciplines like ecology, which studies interactions with the environment; ethology, which looks at behavior; and physiology, which examines how organisms function, focus on different aspects of living beings, taxonomy specifically handles the systematic classification and naming of organisms.
