Question

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?
A) Atmospheric carbon dioxide has no affect on the rate of photosynthesis.
B) The rate of photosynthesis increases with a decrease in carbon dioxide.
C) The rate of photosynthesis increases with an increase in carbon dioxide.
D) The level of carbon dioxide increases with the level of available oxygen

Answer 1

Option C

Step-by-step explanation:

The rate of carbon dioxide influences the rate of photosynthesis in plants. With increased amount of carbon dioxide available, as a substrate required for photosynthesis, the rate of photosynthesis will increase to produce an increase amount of oxygen as the product of photosynthesis.
