Question

Are category and taxon same..if yes how? or no how?

​​​​ please please give me a clear explanation because I couldn't understand the explanation given in NCERT textbook

Answer 1

A taxon (plural taxa) is any taxonomic unit. For example, the class Mammalia is a taxon which includes all mammalian species. Similarly, a species is a taxon, Panthera tigris being the tiger. This taxon contains lower taxa, which are sub-species, such as Panthera tigris tigris (Bengal tiger) or Panthera tigris sumatrae (Sumatran tiger).
Taxonomic category is usually – for better or worse – used interchangeably with the term taxonomic rank. A Dictionary of Biology (6 ed.) certainly indicates that the terms rank and category are equivalent. The major taxonomic categories are domain, kingdom, phylum, class, order, family, genus, and species. A category can contain one or more taxa.

Another example, to summarize:

Carnivora is a taxon, which contains many species including Vulpes vulpes (red fox)
Carnivora is in the category of order
Carnivora (order) is a higher rank than Vulpes vulpes (species)
