16. Crassulacean acid metabolism (CAM) is a type of photosynthesis. A plant using CAM takes in carbon dioxide (CO2) at nighttime, when it is cooler. The plant changes the CO2 into an acid. During the daytime, the plant changes the acid into carbohydrates, without losing water to the warm air. In which environment are such plants best adapted for survival?A. Low-altitude, because the air pressure is greater closer

to sea levelB. Desert, because plants living in the desert have little

water availableC. High-altitude, because the night air is cooler in alpine

zones of mountainsD. Aquatic, because plants living in water need more

carbohydrates to avoid drowning

B.

C.

D.
