C3 plants, accounting for more than 95% of earth's plant species, use rubisco to make a three-carbon compound as the first stable product of carbon fixation. C3 plants flourish in cool, wet, and cloudy climates, where light levels may be low, because the metabolic pathway is more energy efficient, and if water is plentiful, the stomata can stay open and let in more carbon dioxide. However, carbon losses through photorespiration are high.
C4 plants are, so named because they first fix CO2 into a four carbon compound. When the weather is hot and dry, a C4 plant keeps its stomata mostly closed, thus conserveting water. It continues making sugar s by photosynthesis using the pathway.
CAM plants, these species are adapted to very dry climates. A CAM plant conserves water by opening its stomata amd admitting CO2 only at night. Thus, the calvin cyclecan operate, even with the leaf's stomata closed during the day.
