Answer the following questions in terms of physical and/or chemical factors that might explain, or partially explain, various divisions in the Figure 1 classification.
1. The division between the epipelagic and mesopelagic zones.2. The division between the mesopelagic and bathypelagic zones. This boundary is about 1000 meters deep, and it is a level at which many physical and chemical changes occur.3. The division between the supralittoral (above high tide) and littoral zones.4. The division below the sublittoral zone.5. Why is there no boundary at about 1000 meters in the benthic environment but a significant one at about the same depth in the pelagic environment? Think of what the main control on the benthic organisms might be that the pelagic organisms would not have to contend with, and vice versa.
