What is the classification rank that lies below Kingdom and above Phylum?

The classification rank that lies below Kingdom and above Phylum is Class. This hierarchy is part of the biological classification system, also known as taxonomy, which is used to organize all living organisms into categories based on shared characteristics and evolutionary relationships.

In this system, the major ranks from broadest to most specific are Kingdom, Phylum, Class, Order, Family, Genus, and Species. Therefore, Class is positioned directly between Kingdom and Phylum, serving as a way to group organisms that share important features and traits, but are more specific than the kingdom level.

For example, in the animal kingdom, the class Mammalia includes all mammals, which are distinguished from other phyla based on characteristics such as having hair or fur and the ability to produce milk. The Class serves to further classify the diverse organisms within the broad category of a Kingdom, leading to more detailed and specific categories as you continue down the hierarchy.
