While the co2 levels and the temperature increase, the water levels decrease. what effect will this have on the light reactions? and the calvin cycle?

Which plant would stand to gain more from increasing carbon dioxide levels?

in C3 plants, the binding of O2 rather than CO2 by rubisco leads to photorespiration, answering the efficiency of photosynthesis, but C4 plants overcome this problem by concentrating CO2 in the bundle sheath cells at the cost of ATP so rising carbon dioxide levels should benefit C3 plants by lowering the amount of photorespiration that occurs. at the same time, rising temperatures have the opposite effect, increasing photorespiration. but C4 plants are largely unaffected by increasing CO2 levels or temperature

hope this helps.

4, two dominant and two recessive
