What is meant by classification ? Explain the need for classification.

Explanation

Classification is defined on the process which anything is grouped into convenient categories based on some easily observable characters.
It is impossible to study all living organisms. So, it is necessary to devise some means to make this possible. This process is called classification. The scientific term, used for these categories is .TAXA.. Texa can indicate categories at different levels. S.g. Animalia, chordata, mammalia etc. represent taxa at different levels.
Hence based on charactertistics, all the living organisms can be classified into different taxa. This process of classification is called taxonomy. External and internal structures, along with the structure of cell, development processes and ecological information of organisms are essential and they form the basis of modern taxonomic studes, Hence characterisation, nomenclature and classification are the processess that are basic of taxonomy.
To understand the interrelationship among the diversified animal groups, a systamatic classification in necessary.
