Did you know?
WebIn photosynthesis, the energy from the sun is used to turn carbon dioxide (CO2) and water into sugar. Oxygen is a waste product. More light can mean more photosynthesis. It doesn’t necessarily mean more though. When we think of photosynthesis as a process, we can see that there are at least three things that can limit the process: light ...
