Carnivorous plants, commonly referred to as insectivorous plants, are plants that flourish in environments with deficient soil nutrient levels, such as nitrogen.

These insectivorous plants receive the majority of the nutrients necessary for their life by feeding on small insects, rodents, flies, and arthropods.

These plants typically have vibrant colors to draw in prey. Examples include pitcher plants, cape sundew, and the Venus flytrap.

They have a number of trapping devices, including:

1. Pitfall traps

2. Flypaper traps

3. Snap traps

4. Bladder catchers

5. Lobster-pot traps

6. Combination traps

7. Borderline carnivores

Pitcher plants are carnivorous or insectivorous plants. Their leaves are modified as traps. They follow a pitfall trapping mechanism to capture prey. These plants are colorful and attract a wide variety of insects.

The insectivorous plants grow in soil that does not contain sufficient nitrogen minerals. These plants (e.g. pitcher plants) are green and carry out photosynthesis to obtain a part of the food required by them. But they do not get enough nitrogen from the soil in which they grow.

Hence, insectivorous plants feed on insects to obtain the nitrogen needed for their growth.
