Difficulty: MediumTaxonomy and Classification

In the Linnaean system of biological classification, living organisms are organized into nested taxonomic ranks. Which of the following correctly arranges five of these ranks from the broadest category to the most specific category?

  1. A
    Kingdom →\rightarrow Class →\rightarrow Phylum →\rightarrow Order →\rightarrow Family
  2. Kingdom →\rightarrow Phylum →\rightarrow Class →\rightarrow Order →\rightarrow FamilyAnswer
  3. C
    Kingdom →\rightarrow Phylum →\rightarrow Order →\rightarrow Class →\rightarrow Family
  4. D
    Phylum →\rightarrow Kingdom →\rightarrow Class →\rightarrow Family →\rightarrow Order

Answer

Kingdom →\rightarrow Phylum →\rightarrow Class →\rightarrow Order →\rightarrow Family
The sequence 'Kingdom →\rightarrow Phylum →\rightarrow Class →\rightarrow Order →\rightarrow Family' accurately reflects the nested structure of biological classification, moving from the broadest grouping to progressively more specific taxonomic levels.

Step-by-Step Solution

1
Recall the complete Linnaean taxonomic hierarchy from broadest to most specific.
The standard sequence is Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Biological classification arranges organisms into progressively smaller and more specific groupings.
2
Evaluate the sequence of the five ranks provided in the options.
Starting from Kingdom, the correct descending order is Phylum, then Class, then Order, and then Family.
Phylum contains one or more classes, class contains orders, and order contains families.
