light, CO2, temp

• not enough light slows down the rate of photosynthesis
• light provides energy
• as light level is raised the rate of photosynthesis increases - but only to a certain place
• as light increases, the rate will no longer increase as somthing else will become a limiting factor
• the CO2 concentration will increase the amount of rate of photosynthesis up to a certain point . when the graph become flat CO2 is no longer the limiting factor
• if the temperature is too low is normally due to it being too cold for the enzymes to work
