Kingdom: This is the highest taxonomic categories and all organisms are placed in a particular kingdom based on the gross properties as discussed earlier. There are five different kingdoms and few organism as separately kept.

Phylum: Different organisms with similar properties are placed in phylum. For example, phylum chordeta comprises animals containing central notochord for examples: fishes, ambhibians, reptiles, bird etc.

Class: Diffeent classes are present within single phylum. For examples within phylum chordeta, we have individual class for fishes, ambhibians, reptiles etc.

Order: Each class is divided into different order based on the aggregate of character. Each class contains different families. For examples, order carnivore includes families like felidae and cancidae.

Family: Individial order is divided into different families basis of related genra. Foexamples, plants are placed in different families basis of reproductive features of the plants.

Genus: It comprises similar species which has common features. Forexamples, lion, leopard and together are placed within the genus panther.

Species: These are group of organisms with fundamental similarities. Species is the smallest unit in the taxonomic classification. For examples human belongs to species sapiens.
