The level of species.


Life is classified in many levels from less specific to more specific:

  • domain (bacteria, archaea, eukaryotes)
  • kindom
  • phylum
  • class
  • order
  • family
  • genus
  • species

The domains 'contains' the most number of organisms, species contain the least number of organisms (see image).
