Given two areas with equal sunlight and available water. area i has a high
amount of atmospheric carbon dioxide while area il has a low amount of
atmospheric carbon dioxide.
how does the rate of photosynthesis in area i compare to that in area 11?
a)
atmospheric carbon dioxide has no affect 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

The correct answer is the rate of photosynthesis increases with an increase in carbon dioxide.

Explanation:

The amount of carbon dioxide is directly proportional to the rate of photosynthesis that means the photosynthesis rate will increase with increase in the amount of atmospheric carbon dioxide.

   The carbon dioxide undergo reduction by the electrons supplied by the hydroxyl ion(OH-) generated during photolysis of water, to form glucose molecule. Plant utilizes glucose according to its own needs and the excess glucose is stored as starch.
