Question

Why does an insectivorous plant catch or trap an insect?​

Answer 1

To fulfill their need of nitrogen

Answer 2

Answer:

Insectivorous plants trap insects because they grow in soil which is usually thin and is also poor in nutrients, so they eat insects to fulfil their nutrient requirement.

Insectivorous/Carnivorous Plants:

Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods. However, carnivorous plants generate energy from photosynthesis.
