(a) $CO_2$
(b) light
(c) temperature
(d) water
Show Answer
Answer : b
Hints & Solution
(b) According to law of limiting factors given by Blackman, when a process depends upon a number of factors which are separate, the rate of the process is limited by the pace of the slowest factor. Rate of yield is dependent on light as photosynthesis is dependent on light. During monsoon, the intensity of light is less, so rate of photosynthesis is also less, hence yield is reduced.
