Marine Ecosystem

The geography in the ocean is just the same as on the surface. Like sandy plains, mountains, trenches, and much more. There are three different levels in the ocean, The three levels are Euphotic, Bathyal, Abyssal, and each of these levels have different life living there. Euphotic have tiny plants and animals called plankton this level gets a lot of sunlight. Bathyal have whales and other fish living there and it gets little sunlight. Abyssal have lantern fish that has a light on its head that a tracks prey. Those are the marine ecosystem.
