How many levels are in Linnaeus' classification system?

The classification system developed by Carl Linnaeus consists of seven hierarchical levels, which are essential for organizing and naming living organisms in a systematic way. These levels, from broad to specific, are: domain, kingdom, phylum, class, order, family, genus, and species. Each level represents a different rank that helps categorize organisms based on shared characteristics, allowing scientists to communicate more effectively about biodiversity.

The structure of this system builds a framework that makes it easier to classify the vast number of species and understand their relationships. The seven levels in Linnaeus' taxonomy reflect a progression from general categories to more specific ones, with species being the most specific rank. This systematic approach is still widely used today and forms the basis for modern biological classification.
