Light intensity, carbon dioxide levels, and temperature are factors that affect photosynthesis. The rate of photosynthesis
increases as light intensity increases, all of the available electrons are excited at some point and the maximum rate of photosynthesis
is reached and remains the same regardless of further increases in light intensity. When levels of carbon dioxide increase,
photosynthesis is stimulated until it levels off. The rate of photosynthesis increases as temperature increases, peaks at
a certain temperature when many of the enzymes that catalyze the reaction become ineffective, and then decreases.
