Biological Classification of Plants and Animals

• Biological classification of plants and animals was first proposed by Aristotle on the basis of simple morphological characters.

• Linnaeus later classified all living organisms into two kingdoms – Plantae and Animalia.

• Whittaker proposed an elaborate five kingdom classification – Monera, Protista, Fungi, Plantae, and Animalia.

• The main criteria of the five kingdom classification were cell structure, body organization, mode of nutrition and reproduction, and phylogenetic relationships [evolutionary development and diversification of a species].

So, the correct answer is 'Nutrition'.
