Under what circumstances would increasing light intensity not result in an increase in the rate of photosynthesis?
A)At any given time,the rate of photosynthesis is limited by the factor which is in the shortest supply.Therefore,if a factor other than light is limited,increasing the light intensity would not result in an increase in the rate of photosynthesis.
B)At any given time,the rate of photosynthesis is limited by the factor which is in the greatest supply.Therefore,if a factor other than light is in surplus,increasing the light intensity would not result in an increase in the rate of photosynthesis.
C)At any given time,the rate of photosynthesis is at its peak.Therefore,increasing the light intensity would not result in an increase in the rate of photosynthesis.

At any given time, the rate of photosynthesis is limited by the factor which is in the shortest supply. This means that if a factor other than light, such as carbon dioxide or water, is limited, increasing the light intensity would not result in an increase in the rate of photosynthesis. Therefore, increasing light intensity alone is not sufficient to increase the rate of photosynthesis if other limiting factors are present.
