Question

Give scientific classification of cockroach, frog and snake.

Answer 1

Hint: Hierarchy is a term used to enlist rankings. The topmost is the most broader term followed by the others. As we go down the hierarchy, the specification increases and the number of species in them decreases.

Complete answer:
There are diverse animals in our world. To make the study easy, we have divided them into various phyla, classes etc. depending on their specific features.
There is a hierarchy of classification which makes the grouping easy. At the top is the kingdom followed by phylum, class, order, family etc.

Cockroaches are the dirty pests. They can survive without food for 30 days. Cockroaches can not kill us to death but can make us very sick.

Frogs are the amphibians which can live both on land and in water. Their skin is kind of semi-permeable which makes them lose water from their body (dehydration). Thus they prefer to live in a moist area.

Snakes are the reptiles which are boneless and can crawl on the ground. They can be venomous and non-venomous. Cobra, vipers and pythons are the most venomous and dangerous snakes. They are carnivorous in their diet.

Let us learn the hierarchical classification of cockroach, frog and snake.

	Cockroach	Frog	Snake
Kingdom	Animalia	Animalia	Animalia
Phylum	Arthropoda	Chordate	Chordate
Class	Insecta	Amphibian	Reptilian
Order	Blattodea	Anura	Squamata
Family	Blattidae	Ranidae	Colubridae
Genus	Periplaneta	Rana	Serpents
Species	Periplaneta americana	Rana pipens	Python molurus

Note: Whittaker was the one who gave the hierarchical classification. Carolus Linnaeus was the one who started the taxonomic study. This study helps us to name the organisms based on their genus names separating them from organisms from the same family but with different features. In simpler words, we can give them their scientific names which will help us to distinguish them from others.
