Question

Difficulty: MediumTaxonomy and Classification

An environmental scientist is cataloging biodiversity data from a protected forest reserve. Arrange the following taxonomic categories in sequential order from the most specific rank (least inclusive) to the broadest rank (most inclusive).

  1. 1Species
  2. 2Genus
  3. 3Family
  4. 4Order
  5. 5Phylum

Answer

Species → Genus → Family → Order → Phylum
In the standard biological classification hierarchy, the sequence from most specific to broadest is: Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain. Filtering this system for the five ranks provided yields the precise order: Species (most specific), followed by Genus, Family, Order, and Phylum (broadest).

Step-by-Step Solution

1
Identify the most specific taxonomic rank among the given options.
Species is identified as the narrowest biological classification unit consisting of organisms that can interbreed.
The question requires ordering starting from the least inclusive (most specific) category.
2
Determine the intermediate ranks in ascending order of breadth.
Species are grouped into a Genus, related genera are grouped into a Family, and related families are grouped into an Order.
The Linnaean taxonomic hierarchy progresses logically from specific groups to broader ancestral categories.
3
Identify the broadest taxonomic rank among the given options.
Phylum is placed as the final and most inclusive level in this sequence.
Phylum encompasses multiple classes and represents a major organizational division below Kingdom.
