Effect of Lighting and Temperatures on Employee Productivity

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. 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. WebOct 20, 2024 · Light bottle: In the light bottle there is photosynthesis, or Gross Primary Production (GPP), and there is Respiration (R). The difference between these two processes, as we saw above, is Net Primary Production = NPP = (GPP - R) Dark bottle: In the dark bottle there is no photosynthesis and only respiration. easy grip flatware set
