Taxonomic Hierarchy in Biology: Classifying the Mountain Lion

Mary Poffenroth, a biology professor, explains taxonomic hierarchy, a system for classifying organisms. She uses a mountain lion as an example, detailing its classification from domain to species. A mnemonic is provided to help remember the classification order. The video concludes with a call to action for further engagement.
