Taxonomy is the classification of things.

It can refer to the development of a system of classes (called a taxonomy), or to use the system to allocate items into the classes.

Biological taxonomy is the classification of life.

  1. Domain
    There are 3 domains; bacteria, archaea and eukarya.
  2. Kingdom
    There are 6 kingdoms; archaea, bacteria, protista, fungi, plantae and animalia.
  3. Phylum
    There are about 100 to 150 recognized phyla. Examples include anthophyta (flowering plants) and chordata (animals with a notochord).
  4. Class
    There are around 250 to 300 recognized classes. Examples include mammalia (mammals), aves (birds), and insecta (insects).
  5. Order
  6. Family
  7. Genus
  8. Species
    A species is the set group of organisms in which any two appropriate individuals can produce fertile offspring.

domain

There are 3 domains; bacteria, archaea and eukarya.

Bacteria and archaea are unicellular life, from one single prokaryotic cell.

Eukarya are unicellular or multicellular life, from one or more eukaryotic cells.

kingdom

Kingdoms are a classification group below biological taxonomy , domain , kingdom and above phylum.

There are 6 kingdoms; archaea, bacteria, protista, fungi, plantae and animalia.
