Question

Do carnivorous plants still photosynthesize and why are they carnivorous?

Answer 1

Yes, they continue to use photosynthesis.

The nutritional poverty of the soil is the reason that carnivorous plants rely on such elaborate traps: insect prey provides the nitrogen for protein formation that the soil cannot.

Carnivorous plants use their flesh diet to augment their nitrogen supply, but are still autotrophic. (An autotrophic organism produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions.)
