WebJan 16, 2024 · The sunlit zone is also known as the photic or the euphotic zone in the ocean. This sunlit zone is the region of the ocean water that receives the most light from the sun. It’s important to the oceans because it helps carry out photosynthesis and feed most of the marine animals. WebThe ocean is divided into three zones based on depth and light level. The upper 200 meters of the ocean is called the euphotic, or "sunlight," zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles. Only a small amount of light penetrates beyond this depth. church of saint patrick ravena ny
