Question

c4 and cam plants are ________. a. adaptations to arid environments b. adaptations to moist environments c. more common than c3 plants d. less efficient at water conservation than c3 plants please select the best answer from the choices provided a b c d

Explanation:

C4 and CAM plants have evolved mechanisms to reduce water loss. C4 plants spatially separate carbon - fixation processes, while CAM plants temporally separate them (opening stomata at night). Arid environments require such water - conservation adaptations. C3 plants are more common. C4 and CAM are more efficient at water conservation than C3. Moist environments don't need these specific adaptations as much.

Answer:

A. adaptations to arid environments
