* Kingdoms: These are the broadest categories of life. The most commonly used system recognizes five kingdoms: Animalia, Plantae, Fungi, Protista, and Monera (which is often further divided into Bacteria and Archaea).

* Phyla: Phyla are divisions within kingdoms, grouping organisms based on more specific shared characteristics. There are many more phyla than kingdoms, as each kingdom is further subdivided into numerous phyla. For example, the Animal kingdom has over 30 phyla.

* Classes: Classes are even more specific subdivisions within phyla. There are even more classes than phyla, as each phylum is further divided into numerous classes.

Think of it like this:

* Kingdom: The largest box containing all life

* Phylum: A smaller box within the large box

* Class: An even smaller box within the smaller box

Since each kingdom is divided into multiple phyla, and each phylum is further divided into multiple classes, there will inevitably be more phyla and classes than kingdoms.
