How does increasing light intensity affect the rate of photosynthesis?

• It decreases the rate of photosynthesis

• It has no effect on the rate of photosynthesis

• It increases the rate of photosynthesis up to a certain point

• It continuously increases the rate of photosynthesis

At what temperature range does the rate of photosynthesis typically peak?

• 0-10°C

• 15-25°C

• 25-35°C

• 35-45°C

What happens to the rate of photosynthesis if the temperature exceeds the optimal range?

• It remains constant

• It increases

• It decreases

• It stops completely

How does an increase in carbon dioxide concentration affect the rate of photosynthesis?

• It decreases the rate of photosynthesis

• It has no effect on the rate of photosynthesis

• It increases the rate of photosynthesis up to a certain point

• It continuously increases the rate of photosynthesis
