Taxonomic Hierarchy and Classification of Organisms

Mary Poffenroth, a biology professor, explains taxonomic hierarchy, a system for classifying organisms. She uses a grocery store analogy to describe how scientists organize living things. The video details the classification of a mountain lion from domain to species, providing a mnemonic to remember the order. The video concludes with an invitation to explore more biology topics.
