Given two areas with equal sunlight and available water. Areal has a high amount of atmospheric carbon dioxide while Area II has
Mademuasel [1]

Answer:

C. The rate of photosynthesis increases with an increase in carbon dioxide.

Explanation:

Photosynthesis, which is the process by which certain organisms obtain their food from the light provided by the sun, can be inhibited or promoted by certain factors. One of the reactants of the photosynthetic process is carbon dioxide (CO2), hence, an increase in the amount of carbon dioxide, increases the rate of photosynthesis.

According to this question, two areas with equal sunlight and available water are being described to have different levels or amounts of CO2. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide. This means that Area 1 will undergo more photosynthetic activity than Area II.
