12. your classmate is trying to determine the rate of photosynthesis for a fern plant growing in his or her backyard. your classmate wants to set it up in a way for it to have a high photosynthesis rate. which of the following setups has the highest photosynthesis rate? a. low intensity of light, medium levels of carbon dioxide, low temperature level b. high intensity of light, low levels of carbon dioxide, high temperature level c. high intensity of light, high levels of carbon dioxide, moderate temperature level d. medium intensity of light, low levels of carbon dioxide, extremely high temperature level

C. High intensity of light, high levels of carbon dioxide, moderate temperature level

Explanation:

Among all the choices, letter C is the most appropriate combination.

The rate of photosynthesis is controlled by all three factors:

1. amount of light energy

2. concentration of carbon dioxide

3. temperature

4. water

When you think about the Law of limiting factors, the physiological processes the rate at which it occurs will depend on the shortest supply. In terms of photosynthesis, light energy, water and carbon dioxide are needed for the process to occur. Any increase in the materials needed would increase the rate of the process. Temperature is needed because enzymes that catalyze reactions need to be at optimal levels for them to work properly. Usually increasing temperature increases the rate of reaction.
