Study Notes
Taxonomic Hierarchy Overview
- Taxonomic hierarchy is a system for classifying and organizing biological organisms into ranked groups.
- Each rank in the hierarchy reflects the relationship and similarities among organisms.
Domain
- The highest taxonomic rank in the classification system.
- Three main groupings: Archaea, Bacteria, and Eukarya.
Kingdom
- A major taxonomic rank below domain.
- Composed of smaller groups called phyla (or divisions in plants).
Phylum
- Ranks below Kingdom and above Class.
- Particularly important for classifying animals.
Class
- A set or group of organisms sharing common characteristics, attributes, or traits.
- Represents a subdivision of a phylum.
Order
- A taxonomic rank below Class and above Family.
- Comprises families that share similar characteristics or nature.
Family
- Ranks between Genus and Order in biological classification.
- Groups organisms that are closely related.
Genus
- A class or group defined by shared attributes.
- Ranks below Family and above Species.
Species
- The lowest taxonomic rank in the hierarchy.
- Represents the most basic unit of biological classification, defining a group of organisms that can interbreed.
