Pitcher plants grow on less fertile soil. you must remember that plants need several nutrients to manufacture food. For eg Nitrogen. Magnesium is necessary for chlorophyll. Hence to get nutrients, pitcher plants trap insects. When they get digested, nutrients are released. They use these nutrients to manufacture foods. Remember all green plants are AUTOTROPHIC. So is a pitcher plant. Auto means self and Trophism means feeding.
