Over time, what would we expect in the evolution of C3, C4, and CAM strategies?
A. As the most complicated plants, CAM plants are most likely to go extinct.
B. As the probable ancestral form of photosynthesis, C3 plants are primitive and most likely to go extinct.
C. Because CAM plants make better usage of metabolism during the night, they are superior and will eventually become the dominant plants.
D. Because CO2 is delivered by the bundle sheath cells in C4 plants, they are superior and will eventually dominate.
E. Each form of photosynthesis has advantages in a heterogeneous world and, as long as environmental conditions vary, all forms will have an adaptive advantage in their unique niche.
