WebHow does light limit primary productivity? The uppermost layers of the ocean have enough light to sustain the reaction. When the depth increases, the light intensity decreases until it reaches a point where photosynthesis can’t continue. This is the first instance of 1) How does photosynthesis affect productivity? 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.
