In the taxonomy hierarchy, what is the level below phylum?

In the taxonomy hierarchy, the level below phylum is class. Taxonomy is the science of classifying organisms, and it has a defined structure that starts with the broadest categories at the top and becomes more specific as you move down the hierarchy.

The sequence is as follows: Domain > Kingdom > Phylum > Class > Order > Family > Genus > Species. Each level groups organisms based on shared characteristics, with phylum encompassing a broad range of organisms that share certain fundamental traits, while class narrows this group down further, focusing on more specific similarities. Thus, class falls directly beneath phylum in the hierarchy, making it the correct answer.
