Pitcher plants are insectivorous, which means they eat insects.
All species of pitcher plants have watertight tanks which collect water. These watertight containers act as traps for insects and other small creatures. The animals which are attracted to the pitcher's container drown in the watertight body of the plant. The pitcher plant digests the insects using a powerful enzyme which is secreted by the plant. Scientists have noted that all pitcher plants have an amazing array of animals living inside of them.
