Pitcher plants are carnivorous plants. Carnivorous means that the plants feed on insects they trap in their tube-shaped leaves. Once insects get in these tubes, they are trapped and can't get out. These plants are found in places where water is close to the surface and the soil has few nutrients. These plants also need lots of sunshine. Fire is helpful because it kills and removes other plants that might shade the pitcher plants out. Many other interesting plants and animals live in and around these areas.
