All surface waters have a photic zone, where enough sunlight penetrates to support photosynthesis. Oceans and deep lakes also have an aphotic zone, where there is insufficient light for photosynthesis. The benthic zone is the bottom of a lake or ocean. Lakes and oceans are also divided into zones based on distance from shore. Lakes have a littoral zone near shore and a limnetic zone farther from shore. In an ocean, the intertidal zone is alternately submerged and dry during high and low tides, respectively; the neritic zone is near shore, extending from the intertidal zone to the edge of the continental shelf; and the oceanic zone is farthest from shore and therefore does not receive much of the nutrient load from rivers that flow into the ocean.*
