Difficulty: EasyTaxonomy and Classification

In biological classification, organisms are categorized into a tiered hierarchy based on shared characteristics. How should the following taxonomic ranks be arranged in order from the broadest (most inclusive) level to the most specific (least inclusive) level?

  1. 1Kingdom
  2. 2Phylum
  3. 3Class
  4. 4Order
  5. 5Genus

Answer

The correct sequence from broadest to most specific is Kingdom, Phylum, Class, Order, and Genus.
The standard Linnaean system of biological classification arranges taxonomic categories hierarchically from broadest to narrowest: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Arranging the five given ranks from most inclusive to least inclusive yields Kingdom → Phylum → Class → Order → Genus.

Step-by-Step Solution

1
Identify the broadest and most inclusive taxonomic rank listed.
Kingdom represents the largest grouping in this set, encompassing diverse phyla.
Taxonomic hierarchy begins with the broadest category at the top.
2
Determine the intermediate ranks in descending order of inclusiveness.
Phylum is divided into Classes, and each Class is further divided into Orders.
Each successive Linnaean rank groups organisms with increasingly specific shared anatomical and evolutionary traits.
3
Identify the most specific and least inclusive taxonomic rank listed.
Genus is the narrowest category in this group, consisting of closely related species.
Genus sits directly above species, making it the most specific rank among the provided items.
