Classification of Animals – Need and Use

1. To keep the discovered plants and animals in different groups on the basis of their properties so that studies can be done easily.
2. On the basis of the study of the characteristics of an organism of a group, one can get brief information about all the living beings of that group.
3. Naming of all living beings is possible only by classification.
4. It is only through classification that detailed information is obtained about the development of living organisms, their adaptation and the variations generated in them.
5. With the help of classification, any organism or plant can be easily identified, after which it became easy to increase the production of beneficial organisms and get rid of harmful organisms.
