HEYA FRIEND HERE IS YOUR ANSWER
The pitcher plant and Venus fly trap are green plants and can perform the process of photosynthesis but they need to feed on insects for completing their nitrogen requirement and some other nutrients which they cannot get from soil so they feed on insects also.
HOPE IT HELPS YOU!!
Answer:
♦ Carnivorous plants like the pitcher plant, Venus Flytrap and Bladderworts grow in acidic soil which lacks nitrogen, phosphorus, calcium and other nutrients.
♦ These plants can perform photosynthesis and obtain their food from light energy just like other green plants.
♦ However, their nutritional requirements are not fulfilled due to the infertile soil in which they grow.
♦So, they consume insects in order to fulfill their nutritional requirements of nitrogen and other minerals required for survival and growth.
♦ Therefore, Pitcher plant and Venus Flytrap are considered to be partial heterotrophs. They show both autotrophic as well as heterotrophic mode of nutrition.
