You can typically find the walrus living in areas where it is very cold. They are found in the Arctic Ocean as well as the sub Arctic regions as you can guess are cold places. They tend to stay in the shallow parts of the water. When they are hungry they tend to feed at the bottom of the water they are in and so it needs to be no more than 265 feet deep. Some biotic factors which help in the survival of the Atlantic walrus are fish and other animals they eat to get nutrients in order to live, some abiotic factors are the temperature since they are also known to spend half of their time on the layers of ice instead of actually inside of the cold waters. The average temperatures where they reside usually range from 5 degrees Fahrenheit to 40 degrees Fahrenheit.As the temperature increases it causes the natural ability of the Atlantic walrus to migrate as it usually would. Their bodies may not realize that it is time for them to get moving due to the warm weather instead of it being colder. This can result in them being without the food supply that they need to survive in the winter months. It can also make them vulnerable like whales and polar bears. That is because their other sources of food will be less available during some months if the temperature were to change. So in conclusion the change in temperature can cause the decline of the Atlantic walrus population.Explanation of its Interactions The Atlantic walrus is a carnivore as it does not any plants as walruses prefer to eat  molluscs – mainly bivalves such as clams. They also eat many other kinds of benthic invertebrates including worms, gastropods, cephalopods, crustaceans, sea cucumbers, and other soft-bodied animals. Walruses may occasionally prey on fishes such as polar cod. There are some rare walruses which mainly prey on seals. These are usually male walruses, recognizable because they are usually larger than other males, with powerful shoulder and chest muscles. Their skin may become grease-stained from the blubber of the seals they prey on. The Walrus has a commensalism relationship with algae as the algae benefits from the walrus eating food. The algae benefit by consuming the leftover scraps of food left on the walrus tooth or tusk from the last  time they eat. While the algae nenefits from this relationship by getting food to survive it neither benefits or harms the Atlantic walrus, making this a commensalism relationship. Because of their size and tusks, walruses only have two natural predators – killer whales and polar bears. However both predators prefer to attack easier prey like seals. Humanity is historically the greatest hunter of the walrus. During the 1700-1800s the Atlantic population of walruses was hunted to near extinction. So even if the killer whales and polar bears don’t tend to eat the Atlantic walrus it would still be considered as a predation relationship.How its habitat is threatened Over the years the population of the Atlantic walrus has steadily been dropping due to the problems we have created. One is that we are destroying their habitats due to global warming which is a big problem we have created for ourselves. This process seems to make it harder for them to find food. It also takes away the layers of ice that they are able to rest on. Even when the ice is there, it can get thinner so that when a heavy walrus gets on it the ice breaks. Another cause that causes the walrus habitat to be threatened is parasites or a type of virus it can result in high numbers of them being wiped out. The biggest threat to the Atlantic walrus is due to us humans. We continue to take over some of the areas where the walrus lives. Even having noisy machines or airplanes flying over them can create stress and problems for them which can lead to them leaving their natural habitat. The constant presence of it can result in them not breeding, not eating, or trampling others in order to get to the water for safety. This can lead to the decline of the population of the Atlantic walrus making them close to extinction. How its habitat could be repaired
