Most mollusks prefer shallower waters. In shallow waters, the sea floor is also covered with single-celled algae. 9. tall. Ocean decomposers have a variety of methods for gathering dead material to feed on. Phytoplankton are single celled organisms that use photosynthesis to create energy. 30 seconds . The sea ice around Antarctica often has rich growths of algae, often on the underside. There are many other consumers such as whales, Sharks, seals, birds and much more. Tropical oceans like the Pacific have more decomposer organisms than the Atlantic or Arctic oceans because of the warmer temperatures. Fungi is also a big decomposer. The different decomposers can be broken down further into three types: fungi, bacteria, and invertebrates. In the colder ocean waters, only bacteria and fungi do the decomposing because the other creatures cannot survive in the extreme conditions. Seals and sea lions are one of the few groups of marine mammals that live in the Antarctic. Arctic willow is usually 15-20 cm. Trophic Pyramid The Southern Ocean (defined as the area south of the Antarctic Convergence) is one of the most productive areas on Earth - but only during the Antarctic summer (a couple of months around December each year). The sleeper shark and the hagfish are industrious . However, they are not significant food sources for organisms besides decomposers, because most Antarctic life is based in the ocean. Meanwhile, as ocean temperatures rise and the Antarctic sea ice melts, research suggests that krill populations may decrease as the krill are out-competed by salps, barrel-shaped filter feeders .

One well known characteristic of this squid is that it has eight arms, and two longer feeding tentacles. The largest species of whale can be found in Antarctica - the Blue Whale, which is nearing extinction due to over-fishing. It comprises 5.4 million square miles. Decomposers are at the bottom of their respective food chains and usually help to recycle nutrients back into the environment through the process of decomposing matter. Mosses lichens, and fungi are also decomposers but things things take a long tie to decompose in the ocean because there is only a small window of temperatures that would allow activity. The Ross Sea , which has been dubbed the Last Ocean , is still relatively . Consumer: the consumer is zooplankton (middle picture). They break down the chemicals in living things.

Abyssal zone known as the home for many decomposers which feed on bits and pieces of dead stuff that sink down to the bottom. THE ARCTIC OCEAN IS THE WORLD'S SMALLEST. Zooplankton is just one of the many important consumers in the Acrtic Ocean. Since decomposers provide lots of benefits for the plants, it means that decomposers has became the support system to keep the ocean plants alive. Some 700 seaweeds have been reported from the Southern Ocean. Other important decomposers are fungi, marine worms, echinoderms, crustaceans and mollusks. . Others burrow into the soil, like the worm species. Birds Its predators are the Killer Whale and some large sharks.
