Answer:
All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen, and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates.
They mostly divide them by temperature.
Since stomata are affected by [CO2] and water vapor content of the air, an environment with high water vapor content (water potential) and high CO2 levels will likely have the highest #of stomata. I.e. when plants have readily available water source and ample CO2 in order to maximize photosynthesis. As far as geographic environment I think it varies quite a bit and there are competing hypotheses from what I understand
