Question

Which shows the correct descending order of hierarchical classification?

Answer 1

Categories within taxonomic classification are arranged in increasing specificity.The most general category in taxonomic classification is domain, which is the point of origin for all species; all species belong to one of these domains: Bacteria, Archaea, and Eukarya.Within each of the three domains, we find kingdoms, the second category within taxonomic classification, followed by subsequent categories that include phylum, class, order, family, genus, and species.At each classification category, organisms become more similar because they are more closely related.As scientific technology advances, changes to the taxonomic classification of many species must be altered as inaccuracies in classifications are discovered and corrected.
