Carnivorous plants trap insects to counter the deficiency of which element?
Correct answer: D. Nitrogen
- A. Phosphorus
- B. Potassium
- C. Calcium
- D. Nitrogen
Explanation
The pitcher plant (Nepenthes pupurea), Venus flytrap (Dionaea muscipula) and Sundew (Drosera intermedia) are carnivorous or insectivorous plants that grow in soils that lack nitrogenous salts. Hence, these plants prey on insects and other small organisms to meet their nitrogen requirements or needs. These plants have special features like modified conspicuous leaves to attract and trap insects and other organisms. They also produce special secretions to digest their prey.
