The correct answer is the concentrations of carbon dioxide.
Explanation:
The prime elements influencing the rate of photosynthesis are a concentration of carbon dioxide, light intensity, and temperature. A decrease or increase in any of these three elements will straightforwardly influence the rate at which photosynthesis occurs. The enhanced concentration of carbon dioxide will usually upsurge photosynthesis, while a reduction in the concentration will minimize the rate at which photosynthesis occurs.
