What is the order of taxonomic categories from largest to smallest?

The sequence of taxonomic categories from largest to smallest is established based on the hierarchical classification system used in biological taxonomy. The correct order begins with the broadest category, which is Kingdom, and then narrows down to more specific categories: Phylum, Class, Order, Family, Genus, and finally, Species.

This hierarchy is designed to group organisms based on shared characteristics, where higher levels encompass more diverse groups of organisms and lower levels represent more closely related and specific groups. For instance, within the Kingdom Animalia, there are multiple Phyla such as Chordata and Arthropoda, each containing numerous Classes, then Orders, Families, Genus, and ultimately individual Species.

While the other options present a mix-up of these categories, the correct answer correctly reflects the standard taxonomic hierarchy that biologists use to classify living organisms.
