Question

If we keep on increasing carbon dioxide concentration in the air, will the rate of photosynthesis also increase in direct proportion? Yes/No. Explain.

Answer 1

Answer:

Answer. Increase in CO2 increases the rate of photosynthesis but only if not limited by other factors like light and temperature. ... At the same time very high concentration of CO2 becomes toxic to plants and inhibits photosynthesis. So amount of CO2 released decides the rate of photosynthesis.
