Understand that biological classification is a method by which biologists group and categorize species of organisms.
The hierarchical system of classification is known as the Linnaean system, named after Carl Linnaeus, who formalized the modern system of naming organisms.
The correct order of classification from the broadest to the most specific category is: Kingdom, Phylum, Class, Order, Family, Genus, Species.
Each level of classification is called a taxonomic rank, and each rank narrows down the characteristics shared by organisms.
Remember that the sequence is important because it reflects the evolutionary relationships and characteristics shared by organisms at each level.
