1. B. KingdomThe Kingdom is one of the highest ranks in biological taxonomy. It classifies organisms based on basic features like cell type (prokaryotic or eukaryotic), nutrition, and body organization. Examples: Animalia (animals), Plantae (plants), Fungi.2. G. PhylumPhylum groups organisms with similar body structures or organization. For example, Chordata includes animals with a spinal cord, like mammals, birds, and fish.3. D. ClassClass is more specific than phylum. For instance, in the phylum Chordata, the class Mammalia includes animals that have fur and produce milk.4. C. OrderOrder further narrows down organisms within a class. For example, Carnivora is the order that includes meat-eating mammals like cats, dogs, and bears.5. A. FamilyFamily is a group of related genera. For example, the family Felidae includes all cat-like animals such as lions, tigers, and domestic cats.6. F. GenusGenus groups species that are closely related. For example, Panthera is a genus that includes lions (Panthera leo) and tigers (Panthera tigris).7. E. SpeciesSpecies is the most specific level. It refers to organisms that can breed and produce fertile offspring. For example, humans are Homo sapiens.
