Taxonomic hierarchy refers to the arrangement of categories such as kingdom, phylum and class because:

Answer: Each rank fits into an overall scheme reflecting evolutionary relatedness.

  • A Each category is a separate, unrelated grouping of organisms as generally observed
  • B Every level of the hierarchy holds the same number of species under usual circumstances
  • C Each rank fits into an overall scheme reflecting evolutionary relatedness
  • D Categories are arranged mainly in alphabetical order in typical laboratory settings

Correct answer: C. Each rank fits into an overall scheme reflecting evolutionary relatedness

Explanation: Taxonomic hierarchy is the step-wise arrangement of categories (kingdom to species) where each rank reflects a level of relatedness, with broader categories containing more diverse organisms than narrower ones.

The taxonomic hierarchy narrows from Kingdom (broadest, covering the most organisms but fewest shared traits) down to Species (narrowest, fewest organisms but most shared traits) - every level in between is a progressively more specific subset of the one above it.
