Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If the amount carbon dioxide is increased what happens to the rate of photosynthesis?
A
it increases
B
it decreases
C
it doesn’t change
D
it is not affected
Explanation: 

Detailed explanation-1: -Elevated [CO2] increases the availability of carbon in leaves causing greater Rubisco activity and higher rates of photosynthesis.

Detailed explanation-2: -Carbon dioxide and rate of photosynthesis 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-3: -By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise.

Detailed explanation-4: -1 Answer. The rate of photosynthesis will decrease as the amount of CO2 decreases.
