PHOTOSYNTHESIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The rate of photosynthesis decreases as the
A
oxygen concentration decreases
B
carbon dioxide concentration decreases
C
light intensity increases
D
temperature becomes moderately warm
Explanation: 

Detailed explanation-1: -An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.

Detailed explanation-2: -The rate of photosynthesis will decrease as the amount of CO2 decreases.

Detailed explanation-3: -If the temperature decreases, the rate of photosynthesis will decrease as enzyme activity slows. If the temperature increases, the rate of photosynthesis increases. If the temperature is too high, enzymes will denature, causing photosynthesis to slow drastically.
