Final answer:
Biological classification is a system that categorizes living organisms based on their similarities and differences at multiple hierarchical levels, including domain, genus, and species.
Step-by-step explanation:
Biological classification is a system that categorizes living organisms based on their similarities and differences. It involves grouping organisms into different hierarchal levels, starting with the most inclusive level called domain, followed by kingdom, phylum, class, order, family, genus, and species. Domain is the highest level in the biological classification hierarchy, representing the broadest category of organisms. Genus and species are the most specific levels, identifying individual species within a genus.
