Given two areas with equal sunlight and available water. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide.
How does the rate of photosynthesis in Area I compare to that in Area II?
Atmospheric carbon dioxide has no effect on the rate of photosynthesis.
The rate of photosynthesis increases with a decrease in carbon dioxide.
The rate of photosynthesis increases with an increase in carbon dioxide.
The level of carbon dioxide increases with the level of available oxygen.
