Question

19. If we keep on increasing CO, concentration in air what will be the rate of photosynthesis?​

Answer 1

Explanation:

Increase in CO2 increases the rate of photosynthesis but only if not limited by other factors like light and temperature. ... This increase is observed up to 1% of CO2 concentration. At the same time very high concentration of CO2 becomes toxic to plants and inhibits photosynthesis.
