Identification means correctly working out which known organism a specimen is. NCERT says an organism is identified only when it is described correctly AND we know to which organism the name is attached. So you describe the features, then match those features to a named, already-known organism.
NCERT lists four processes basic to taxonomy: characterisation, identification, classification and nomenclature. Characterisation is noting the features, identification is matching to a known organism, classification is placing it in groups, and nomenclature is giving it a scientific name.
No. Identification answers 'which organism is this?' by matching one specimen to a known organism. Classification answers 'which group does it belong to?' by placing organisms into categories like genus, family and kingdom. Identification usually comes first; classification groups many organisms together.
Because naming and grouping only make sense once you know what the organism is. If you have not correctly described the organism and matched it to a known type, you cannot give it the right scientific name or put it in the correct group. So identification is the base step that makes nomenclature and classification possible.
Taxonomic aids help identification. A taxonomic key uses pairs of contrasting characters (couplets) to narrow down the organism step by step. Flora, manuals, monographs, herbaria and museums also store described specimens that you compare against your unknown organism.

Yes. Identification is one of the four basic processes of taxonomy, along with characterisation, classification and nomenclature.
Identification comes first. You must correctly identify an organism before you can give it the right scientific name (nomenclature).
A taxonomic key is used for identification. It uses pairs of contrasting characters to lead you step by step to the correct organism.
The word 'identification' rarely appears alone in a NEET question, but its partner processes (nomenclature, classification, taxonomic keys) are asked often, so you must know all four processes of taxonomy.
