The benthic zone begins at the edge of the sea at the intertidal zone, extends out along the continental shelf, and continues down the continental slope to the abyssal plain, thousands of meters below sea level.
Organisms in the photic zone include water plants and phytoplankton, microscopic algae and bacteria that carry out photosynthesis.The deep areasof a lake, where light levels are low, are called the aphotic zone. The bottom ofany aquatic ecosystem is called the benthic zone.
