A Venus flytrap is a producer. You see, the flytrap does not really EAT the insects that it catches. It decomposes them and uses their chemicals like fertilizer. These plants are designed to live in very poor soil, so they cannot get the chemicals they need for their biological processes from the soil. Thus, they get them from the insects they keep. However, they do not use the insects for food. They produce their own food through photosynthesis, just like other plants.
