Final answer:
Hierarchical classification is a principle of taxonomy that organizes living organisms from broad domains to specific species in a structured system.
Step-by-step explanation:
The concept being described is known as a hierarchical classification system, which is a fundamental principle of taxonomy. Taxonomy uses a structured system starting with broad categories and moving towards more specific ones. For example, in the taxonomic classification system, we start with large groups called domains and narrow it down through kingdoms, phyla, classes, orders, families, genera, and eventually to species.
