Here's a breakdown of the classification levels from broadest to most specific:
* Domain: The highest level, grouping organisms based on fundamental cellular differences. (e.g., Bacteria, Archaea, Eukarya)
* Kingdom: Groups organisms within a domain based on general characteristics. (e.g., Animalia, Plantae, Fungi)
* Phylum: Groups organisms within a kingdom based on shared body plan features.
* Class: Groups organisms within a phylum based on more specific characteristics.
* Order: Groups organisms within a class based on shared traits.
* Family: Groups organisms within an order based on close relationships.
* Genus: A group of closely related species.
* Species: The most specific level, defining a group of organisms that can interbreed and produce fertile offspring.
