What is the major taxonomic rank that is above phylum and below domain?

The major taxonomic rank that is above phylum and below domain is kingdom. In the hierarchical classification system of living organisms, the order of ranks starts from domain, which is the broadest category. Following domain, the next category is kingdom, and then it is followed by phylum, class, order, family, genus, and species.

Kingdom serves as a critical organizational level as it groups together related organisms that share fundamental characteristics and evolutionary history. For example, within the domain Eukarya, there are several kingdoms, including Animalia (animals), Plantae (plants), and Fungi (fungi), each representing a diverse range of life forms that are more closely related to each other than to those in other kingdoms.

In contrast, class, order, and family are ranks that fall below kingdom in this hierarchy, making them less inclusive as they subdivide organisms into more specific categories.
