Explanation:
Detailed explanation-1: -The temperature required for photosynthesis varies from 10°-40° C depending upon the habitat. The optimum temperature required for photosynthesis ranges 25°-35° C.
Detailed explanation-2: -Hence if the temperature is increased to more than 35oC there will be a decline in the rate of photosynthesis due to denaturation of carbon fixing enzymes. Similarly, at very high temperatures, the rate of respiration also falls significantly.
Detailed explanation-3: -When the temperature is increased from minimum to optimum, rate of photosynthesis doubles for every rise in temperature.
