Insectivorous plants are found
Answer: D
Insectivorous plants are found in nitrogen deficient places.
Plants such as the pitcher plant (Nepenthes), sundew (Drosera), bladderwort (Utricularia) and Venus flytrap grow in bogs, marshes and poor, acidic soils that lack nitrogen. They photosynthesise normally, but trap and digest insects to obtain the nitrogen (and some other nutrients) that the soil cannot supply.
They are not short of carbon, which they fix from the air, or of oxygen; and although such soils may also be poor in phosphorus, nitrogen deficiency is the classic textbook reason for insectivory.
