(2) mode of nutrition
Solution
As per NCERT, R.H. Whittaker (1969) proposed the five kingdom classification: Monera, Protista, Fungi, Plantae and Animalia.
∵ The main criteria were cell structure, body organisation, mode of nutrition, reproduction and phylogenetic relationships.
⇒ Among these, the mode of nutrition (autotrophic, heterotrophic – saprophytic/parasitic, holozoic) was the main basis that separated Fungi, Plantae and Animalia.
∴ The main basis of classification is the mode of nutrition.
