Question

If the pitcher plant is green and carries out photosynthesis, then why does it feed on insects?​

Answer 1

Explanation:

The insectivorous plants grow in soil which do not contain sufficient nitrogen mineral. These plants (e.g. pitcher plant) are green and carry out photosynthesis to obtain a part of the food required by them.So, insectivorous or carnivorous plants feed on insects to obtain the nitrogen needed for their growth.

Answer 2

Answer:

Pitcher plant contains chlorophyll, hence it can do photosynthesis and prepare its own food. Pitcher plant grows in swamps, bogs areas where the soil is deficient in nitrogen mineral. So it traps the insect and utilize their proteins die to nitrogen deficiency. Therefore its an insectivorous plant.
