Illustrate the taxonomical hierarchy with suitable examples of a plant and an animal.
Solution and Explanation
The arrangement of various taxa in a hierarchical order is called taxonomic hierarchy.
In this hierarchy, species is present at the lowest level whereas kingdom is present at the highest level.
Classification of a plant
As an example, let us classify Solanum melongena (Brinjal).
Kingdom - Plantae
Division - Angiospermae
Class - Dicotyledonae
Order - Solanales
Family - Solanaceae
Genus - Solanum
Species - melongena.
Classification of an animal
As an example, let us classify Columba livia (Blue rock Dove).
Kingdom - Animalia
Phylum - Chordata
Class - Aves
Order - Columbiformes
Family - Columbidae
Genus - Columba
Species - livia.
