Carnivorous plants fulfill their nutritional requirements by feeding on small animals, like insects or protozoan’s. E.g., Nepenthes, Venus fly trap, Utricularia, etc. Carnivorous, plants grow in soil deficient in nitrogen. Pitcher plant in pitcher plant leaves are modified into pitcher which stores the juice to lure an insect. When an insect comes to suck this juice, chemicals present in nectar dissolves the skin of the prey and the plant obtains nutrients (mainly nitrogen) from its skin.
