Summary1.The oxygen consumption of some profundal and other muddwelling animals was studied in relation to . Most photosynthesis occurs in this zone. A lake ecosystem or lacustrine ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (non-living) physical and chemical interactions. The deeper down along the thermocline, the lowest the oxygen levels, so the epilimnion contains the highest levels of oxygen and the hypolimnion the lowest levels. This is the zone of the ocean that is most exposed to light, and as a result, it has the largest populations of marine life. Anglerfish, deep sea jellyfish, deep sea shrimp, cookiecutter shark, tripod fish, and abyssal octopus, sometimes known as the dumbo octopus, are some of the animals that live in this Required fields are marked *. When goldfish are placed in a rotating annular chamber of which the outer wall is glass, they can be induced to swim steadily at a rate which varies with the temperature when the water is aerated. Light does not reach the Profoundal Zone so there is not a lot of diversity in the area. The aphotic zone exists in depths below 1,000 meters (3,280 feet). What is the abyss in the ocean?
