What environmental variables might affect the net rate of photosynthesis? Why do you think they would affect it? How do you predict they would affect it?

1. Temperature

2. Amount of light (light intensity)

3. Amount of carbon dioxide exposure

Explanation:

1. Increase in temperate would decrease the net rate of photosynthesis.

2. Light is required to excite the photons in the process of photosynthesis, therefore if light intensity levels are low, the net rate of photosynthesis would be slow.

3. Carbon dioxide is required for photosynthesis to take place therefore enough carbon dioxide levels would increase the rate of photosynthesis.
