Vedclass · Answer

(C) According to Blackman's Law of Limiting Factors,if a chemical process is affected by more than one factor,then its rate will be determined by the factor which is nearest to its minimal value: it is the factor which directly affects the process if its quantity is changed.In nature,$CO_2$ concentration is usually the major limiting factor for photosynthesis because its atmospheric concentration is very low $(0.03-0.04\%)$ compared to the requirement for optimal photosynthetic activity. While light and temperature also affect the rate,$CO_2$ is frequently the limiting factor under natural conditions.

In nature,the rate of photosynthesis is primarily limited by which of the following factors?
