A: shrubs.
B: crabgrass.
C: ferns.
D: weeds.
E: cacti.

Answer 1

CAM plants include cacti and other succulents, which have a unique adaptation called Crassulacean Acid Metabolism (CAM) that allows them to avoid water loss.

Step-by-step explanation:

CAM plants include cacti, such as the jade plant, and other succulents. These plants have a unique adaptation called Crassulacean Acid Metabolism (CAM), which allows them to avoid water loss by fixing CO₂ only at night. During the day, they close their stomata to conserve water. Leaf structure and fixation pathways in CAM plants differ slightly from other plants, but all three carbon fixation pathways lead to the Calvin cycle to build sugar.
