Which of the following statements is not correct regarding Blackman’s law of limiting factors ?
The factor closest to its optimum value is the limiting factor.
If a limiting factor is increased, the rate of the process increases until another factor becomes limiting.
When a biological process is affected by several factors, its rate is determined by the factor which is present in the minimum amount.
It is applicable to both physical and biological processes.

The major limiting factor for photosynthesis is
Light
Increasing the concentration of carbon dioxide around a plant will MOST likely increase the rate of photosynthesis up to a certain point, because:
CO2 is a reactant in photosynthesis.
CO2 is a product of photosynthesis.
CO2 absorbs light energy.
CO2 regulates the opening and closing of stomata.
A plant is exposed to green light only. Which of the following is most likely to occur?
The rate of photosynthesis will be significantly reduced.
The rate of photosynthesis will be at its maximum.
The rate of photosynthesis will be slightly increased.
The rate of photosynthesis will remain unaffected.
