Biological classification: which sequence correctly represents the standard hierarchy (broad to specific)?
-
APhylum, kingdom, class, order, genus, species, family
-
BKingdom, phylum, class, order, family, genus, species
-
CKingdom, phylum, family, class, order, genus, species
-
DClass, order, kingdom, phylum, family, genus, species
Answer
Correct Answer: Kingdom, phylum, class, order, family, genus, species
Explanation
Introduction / Context:Taxonomy organizes biological diversity from broad categories to very specific ones. Correct ordering is often tested using mnemonics like “King Philip Came Over For Good Soup.”
Given Data / Assumptions:
- The classic Linnaean ranks are expected.
- Domain level is omitted here (acceptable for many exam contexts).
Concept / Approach:The standard sequence from broadest to most specific is Kingdom > Phylum > Class > Order > Family > Genus > Species. Each rank narrows classification based on shared characteristics.
Step-by-Step Solution:
Start with the broadest category: Kingdom.Then proceed downward: Phylum, Class, Order, Family, Genus, Species.Compare each option to the canonical order and select the exact match.Verification / Alternative check:Use the common mnemonic or consult a taxonomy chart; both confirm the order in option B.
Why Other Options Are Wrong:
- A, C, D: Misordered ranks break the broad-to-specific sequence.
Common Pitfalls:Mixing Family and Order or placing Kingdom after Class. Remembering a mnemonic eliminates these mistakes.
Final Answer:Kingdom, phylum, class, order, family, genus, species
