Why hierarchiral taxonomic system is used?
As each higher taxonomic category contains it is below groups/categories
It is helpful to established classifications
All taxonomic categories reflect common habitats
Taxonomic group shows similar characters and have no evolutionary relationship
In a taxonomic hierarchy, family is interprepated between
Kingdom and class
Class and order
Order and genus
Class and genus
The suffix ‘phyta’ indicates
Family
Class
Order
Division
