Most plants obtain nutrients from the soil via their roots. However, carnivorous plants have specialized features that allow them to access nutrients by trapping and digesting insects. Many of these plants are native to swamp and bog areas of North America.

Teaching your students about carnivorous plants is a great way to explore plant adaptations and ecosystem interactions. Additionally, learning about such unique plant life stirs their imagination and sparks investigation. Two common carnivorous plants you may want to explore are:

Venus Fly Trap. The leaves of a Venus flytrap resemble an open trap. When insects land on the leaves, they brush past small hairs that trigger the leaves to close over the unsuspecting visitors. The leaves secrete a digestive enzyme that breaks down the insect, releasing nutrients that are then absorbed by the plant.

Pitcher Plant. The pitcher plant resembles a long tube. Insects are drawn to the sugary nectar produced within this tube, but once they're inside they become trapped in the tube. Digestive enzymes then break down the insect, making nutrients available to the plant.
