What is common to Nepenthes, Utricularia and Drosera with regard to the mode of nutrition?
All of these are insectivorous plants. These plants supplement their nutrient intake by trapping and digesting small organisms, such as insects or microscopic prey, to obtain essential nutrients like nitrogen and phosphorus, which are often deficient in their poor soils. Nepenthes traps its prey using pitcher-shaped structures.
Utricularia utilizes suction traps resembling small bladders.
Drosera ensnares insects with sticky, hair-like glands on their leaves.
