Detailed explanation-1: -Plants take in carbon dioxide from the air. But, since the amount of CO2 in the air is very less, it acts as a limiting factor for photosynthesis. It is seen that, when light and temperature are not the limiting factors, increasing CO2 concentration leads to an increase in the rate of photosynthesis.
Detailed explanation-2: -# 43 Effect of Carbon Dioxide on the Rate of Photosynthesis When the concentration of CO2 is low the rate of photosynthesis is also low. (the plant has to spend time waiting for more CO2 to arrive). Increasing the concentration of CO2 increases the rate of photosynthesis.
Detailed explanation-3: -Elevated [CO2] causes increased photosynthesis in plants, which leads to greater production of carbohydrates and biomass.
Detailed explanation-4: -Another limiting factor is carbon dioxide concentration. Carbon dioxide and water are what the plant converts into glucose, and so without enough carbon dioxide, the process cannot occur. As levels of carbon dioxide increase, the rates of photosynthesis also increase.
