IGCSE Biology Notes - The Taxonomic Hierarchy - Human Hierarchy

Once you named an organism you have to assign an appropriate position in a systematic frame work of classification. This frame work is called taxonomic hierarchy by which the taxonomic groups are arranged in a definite order from higher to lower categories. Each category in the hierarchy is considered as a taxonomic unit and is known as taxon.
Taxonomic Hierarchy
  • The categories used in the classification of animals are 
                               Kingdom, Phylum, Class, Order, Family, Genus , Species. 
  • BE4U TIPS :     King      Philip     Came  Over    For      Good    Spinach
  •  These categories are ranked on above the other, called Hierarchy.
  • Kingdom is the highest and species is the lowest category in this hierarchy.
