Vedclass · Answer

(C) According to Blackman's Law of Limiting Factors,the rate of a physiological process is limited by the factor that is present in the least amount relative to its optimum requirement.In the atmosphere,the concentration of $CO_2$ is very low $(0.03-0.04\%)$,which is far below the saturation point for photosynthesis in most $C_3$ and $C_4$ plants.Therefore,$CO_2$ concentration is the major limiting factor for photosynthesis under normal field conditions during the day.

Which is the major limiting factor for photosynthesis during the day?
