Which is the smallest or basic rank in taxonomic hierarchy?

Answer and explanation

Correct answer: Species

Direct answer: C, Species. In the usual taxonomic hierarchy, species is the smallest and most specific basic category. Closely related species are grouped into a genus; related genera form a family; families form an order, and higher categories continue above them. A species is commonly described as a group of similar organisms that can interbreed under natural conditions and produce fertile offspring, although biological definitions can have limitations in special cases. A, genus, is one level above species and contains one or more closely related species. B, family, is broader than genus and includes related genera. D, order, is broader still and includes related families. Thus the movement from narrow to broad begins with species, not genus, family, or order. Memory cue: “Species starts the specific-to-broad ladder.” Do not confuse the smallest basic rank, species, with the first word of a binomial name, which is the genus.
