Which one of the following is the first step in taxonomy ?

Correct Answer :

Identification is determining the correct place in a system of classification and finding out the correct name of the organism. It is carried out with the help of keys. It not only assigns the organism to a particular group, locate its correct name but also provide information if the organism is new to systematics and requires giving a new name.
