Factors that affect photosynthesis
There are factors that affect the process of photosynthesis: temperature, CO2 concentration, and light intensity. When temperature is high, the rate of photosynthesis goes up. But then, if it passes some level, the rate will suddenly drop and it won`t work anymore. When light intensity goes up, the rate will also go up. But when it reaches certain level, the rate will be steady. Same thing happens to CO2 concentration. When CO2 concentration goes up and the rate reaches maximum, the rate will be just stable.
