How does light availability affect primary production?

WebIn Photosynthesis, plants use the sun's energy as light to transform carbon dioxide and water into glucose. In cellular respiration, glucose is ultimately broken down to yield carbon dioxide and water, and the energy from this process is stored as ATP molecules. WebJan 22, 2024 · Light. Energy from the sun is essential to the process of photosynthesis, by which most primary production gets done. This has a large effect in the oceans, where, because of the limits of light penetration, it is necessary for most production to take place near the surface.
