Question

In cold and foggy area, the limiting factor is
A: temperature
B: light
C: both a and b
D: none of these

Answer 1

Answer:

light is the answer hope it helps

Answer 2

C:both a and b

LIGHT and TEMPERATURE are the limiting factors in cold and foggy area.

Explanation:

Rate of photosynthesis depends on TEMPERATURE, LIGHT and other environmental factors. If all factors are not present in required amount then photosynthesis will not happen at its maximum rate, and deficiency of any one factor will also limit photosynthesis.

TEMPERATURE: An increase in temperature increases the kinetic energy of the molecules and thus rate of reaction increases resulting in high rate of photosynthesis to happen.

LIGHT: Light is directly proportional to rate of photosynthesis. At lower intensity of light rate of photosynthesis also decreases. On hotter days the rate of photosynthesis is high as compared to that on cooler days.

• If any single of these factors are less then rate of photosynthesis will be effected and thus either a or either b is incorrect. Option d is also incorrect because both a and b are limiting factors for cold and foggy areas.
