Which is the first classification term used in the material as a grouping within the kingdom?

• A. Family
• B. Class
• C. Phylum
• D. Order

Answer: (C)

When you organize living things, you start with broad groupings and get more specific as you go down. After placing organisms into a kingdom, the next level of grouping is the phylum. Phylum groups organisms that share major structural features or body plans, which helps explain broad similarities and differences across large groups. For example, in animals, phyla include groups with distinctive characteristics like having a backbone (Chordata) or having segmented bodies (Arthropoda). The levels that come after phylum—class, then order, then family—are progressively more specific, narrowing down from broad body plans to closely related organisms. So the first classification term used within the kingdom is phylum. The other terms listed—class, order, and family—appear after phylum in the hierarchy; they represent successively narrower groupings. (Note: in plants, division is sometimes used instead of phylum, but phylum is the standard term for many organisms.)
