WebThe correct answer is C because: - At 1 , the rate of photosynthesis has yet to level off (neither temperature or concentration of carbon dioxide are limiting in this experiment) so light intensity is still the limiting factor. - At 2, the rate of photosynthesis is no longer increasing even though light intensity is still increasing, so some other factor is limiting (in … WebHere we review how photosynthesis, photorespiration and respiration are affected by increasing atmospheric CO 2 concentrations and climate warming, both separately and in combination. We also compile data from the literature on plants grown at multiple temperatures, focusing on net CO 2 assimilation rates and leaf dark respiration rates …
