2. A student is completing an experiment comparing plants in two areas. Both areas have the same type of plants with equal sunlight and equal available water. Area 1 has a high amount of carbon dioxide in the atmosphere and area 2 has a low amount of carbon dioxide in the atmosphere.
How does the rate of photosynthesis in area 1 compare to the rate of photosynthesis in area 2?

A. The rate of photosynthesis decreases with an increase in carbon dioxide, therefore, area 1 will have a lower rate of photosynthesis compared to area 2.
B. The rate of photosynthesis increases with an increase in carbon dioxide, therefore, area 1 will have a higher rate of photosynthesis compared to area 2.
C. The amount of carbon dioxide in the atmosphere has no affect on the rate of photosynthesis, therefore, area 1 and area 2 will have the same rate of photosynthesis.
D. The rate of photosynthesis increases with a decrease in carbon dioxide, therefore, area 1 will have a lower rate of photosynthesis compared to area 2.

Answer 5

B. The rate of photosynthesis increases with an increase in carbon dioxide, therefore, area 1 will have a higher rate of photosynthesis compared to area 2.
