Insectivorous or carnivorous plants are the one who feed by eating other living organisms such as insects. They are able to attract and trap the organisms by the specific trapping techniques, there are six types of different techniques such as adhesive, pitfall, lobster pot, pigeon trap, snap, suction which helps them in catching the prey.

Complete answer:
- Nepenthes are insectivorous which use pitfall traps.
- Pitfall traps are leaves changed into pit-like structures. The Bromeliad carnivores (Brocchinia and Catopsis) are the handiest pitfall traps where the base of the whorl of leaves seal to form a cup to seize water.
- Prey slip down the leaves into the pool at the bottom and drown. The different carnivores with pitfall traps have particularly changed leaves where every leaf is a separate entice.
