The atmosphere contains 0.03% of carbon dioxide amidst other gases. 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. Experiments have been performed to study the rate of photosynthesis on increasing the concentration of CO2 in the atmosphere. 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. But, beyond a certain limit, CO2 starts accumulating in the plant and this leads to slowing down of the process. So, excessive CO2 inhibits photosynthesis especially when it starts to accumulate.
