This region includes the photic zone, where sunlight penetrates and supports productive plankton populations at the surface; the benthic zone, where bottom-dwelling organisms live in seagrass beds and reefs; and the coastal zone, which includes the interface between land and sea and extends out to the continental shelf. The abyssal zone, which is the deepest and least productive part of the ocean, and the intertidal zone, which is the area between high and low tide, are not included in this region.
