The principle of limiting factors as applied to the effects of temperature, carbon dioxide concentration and light intensity on the rate of photosynthesis.

There are certain things that are needed for photosynthesis to take place. The availability of these things affects the rate of reaction.

If there is a lack of something that is needed then the rate of reaction will decrease, making it a limiting factor.

Temperature can be a limiting factor because heat energy increases kinetic energy and therefore there are more collisions and so more enzyme-substrate complexes formed.

Temperature directly correlates to rate of photosynthesis until it gets over a heat where it will denature enzymes; then the rate will decrease as there are fewer enzymes to aid the reactions.

Carbon dioxide is a chemical used so the more of it there is the more reactions can be done and visa versa.

Light intensity has an effect because the protons from light are what power the light-dependent reaction, so if there is not enough light the process will happen less frequently.
