WebPrimary production is of course a function of light or more precisely the photon flux density that can be absorbed by the phytoplankton photosynthetic pigments. It is therefore, both the intensity and spectral composition of the light that influences the rate of photosynthesis. 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.
