Which concept refers to a category or group of organisms within a classification system?

• A. Binomial nomenclature
• B. Taxon
• C. Taxonomy
• D. Paradigm

Answer: (B)

In biology, life is organized into named groups called taxa at various levels, such as species, genus, family, and so on. A taxon is any such named category within that classification system, so it directly refers to the category or group itself. Binomial nomenclature is the two-part naming method for species, taxonomy is the field that studies classification, and paradigm is a broad framework used in science; none of these names the group in the hierarchy as a taxon does. So the term that best fits the idea of a category or group within a classification system is taxon.
