Organism Classification (/biology/organism_classification)

An organism classification is a set of living things, (e.g., plants, animals, microorganisms), that has a classification rank, (e.g., Kingdom, Phylum, Class, Order, Family, Genus, Species). All classifications, from the lowest classification (sub-species, cultivars, breeds and varietals) up to the highest classification (Domain), are organism classifications. The organism classification type should not be used for an individual organism, such as household pets, animal performers, racehorses, even named plants. Use the organism type for that.
