Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these are limiting factors for photosynthesis? Choose 3 answers.
A
Light intensity
B
CO2 concentration
C
Temperature
D
Light
E
CO2 levels
Explanation: 

Detailed explanation-1: -Limiting factors for the photosynthesis are temperature, carbon dioxide levels, and light intensity. Photosynthesis will decline if temperature and light intensity is too low or high.

Detailed explanation-2: -The rate of photosynthesis can be affected by various limiting factors such as light intensity, carbon dioxide concentration, temperature and water availability.

Detailed explanation-3: -Temperature affects all reactions because an increase in temperature causes the molecules involved to gain kinetic energy and therefore react more frequently. However, a very high temperature can denature the enzymes involved in these reactions, reducing or even stopping the reaction completely.
