How do carbon dioxide concentration, temperature and light intensity affect the rate of photosynthesis?

Answer 1

To find the answer to this question, we can use Le Chatelier’s principle to see how the rate of photosynthesis will be affected.

For carbon dioxide concentration, we can see that carbon dioxide is a reactant of photosynthesis, so increasing a reactant will cause an increase in products, and therefore the rate of photosynthesis will increase.

For temperature, we can see that energy is required to make photosynthesis happen, so temperature can be seen as a reactant. This will cause an increase in products, and thus the rate of photosynthesis will increase.

For light intensity, the same principles as above can be applied to see that the rate of photosynthesis will increase.
