  • B.cold environment
  • C.low-nutrient environment
  • D.high-nutrient environment

Answer: C

Insectivorous plants are adapted to a low-nutrient environment.

Plants such as the pitcher plant, sundew, Venus flytrap and bladderwort grow in bogs, swamps and poor soils that are deficient in nitrogen. They photosynthesise normally but trap and digest insects to obtain the nitrogen and other minerals the soil does not supply.

Their adaptation is to nutrient poverty, not to dryness or cold, and in high-nutrient soils they would have no advantage.

Their leaves are modified into traps, such as pitchers, sticky glandular hairs, snapping lobes or bladders, and secrete enzymes that digest the proteins of the captured prey.
