WebWhat does change, however, is the ratio between red and far-red. If we look back at the top of the canopy in graph 1, there are roughly equal amounts of red and far-red (which is in the range between 700-800nm), as we go down that ratio changes quite dramatically: there is relatively more far-red as we go down in the canopy. WebThe euphotic zone is the upper part of the ocean that receives bright and clear sunlight (Fig. 9.5). In clear tropical waters, the euphotic zone may extend to a depth of 80 meters (m). Sunlight does not penetrate as deeply near the poles, so in these areas the euphotic zone may be less than 10 m deep.
