The process of classification of all living organisms on the basis of their characteristics is called taxonomy.
The processes carried out in taxonomy are as follows:
(a) The organism has to be described for its all morphological, anatomical, physiological and behavioural properties.It is called as characterisation.
(b) On the basis of its characters, it is decided whether it is similar or different to any known group of taxa.It is called identification.
(c) Based on similar characteristics, it is then placed in a known taxa. It is called classification.
(d) When the organism is placed in the right taxa, the last step is to determine its name. This is called as nomenclature.
