Order K is a classification used in biology to categorize organisms based on shared characteristics. It is part of the hierarchical system of taxonomy, which includes ranks such as domain, kingdom, phylum, class, order, family, genus, and species. Order K helps scientists organize and identify species, making it easier to study their relationships and evolutionary history. In the context of taxonomy, Order K can refer to various specific orders within different classes. For example, in the class of mammals, there are orders like Carnivora and Primates. Each order groups together species that share common traits, aiding in the understanding of biodiversity.
