Abiotic VS Biotic

Abiotic

Abiotic factors are the non-living components in an ecosystem. There are not many abiotic factors in a region like the Arctic Ocean since many abiotic factors are man-made, and there are hardly any people there.

There is, however a large quantity of water/ice. Most of the Arctic Ocean's surface consists of drifting ice packs, vast ice floes and ice burgs.

Approximately 25% of the undiscovered petroleum is believed to be located at the bottom of the Arctic Ocean.

Although it may not come to mind as an important component of the Arctic Ocean, the sun is always one of the most significant parts of an ecosystem. It is what permits any biotic factors to survive.




Biotic

Biotic factors are anything living in an ecosystem and their remains. The weather prevents many animals from living there, but there are many species that have adapted to the cooler weather, and there are some that would not even be able to survive in warm weather.

Plankton are organisms with only one cell that float in the water column. They function just like plants in a terrestrial ecosystem. Some kinds of plankton include; diatoms, dinoflagellates and protist. Planktons such as phytoplankton are producers and some smaller fish like krill will eat them.

There are many types of whales in the Arctic Ocean, like Belugas, Bowhead Whales, Grey Whales or Narwhals, but the most popular ones are Humpback whales. They eat krill and small schooled fish. The only predators they have are killer whales, who tend to only feed on the younger and smaller Humpback whales.

A polar bear is actually a big part of the Arctic Ocean as it spends most of its time on the ice fishing for meals, such as; seals, fish and seabirds. Mothers will spend most of their time trying to feed their children, so they are often near the surface of the water, and is still included in the ocean's food web.

A walrus will live deep in the Arctic Ocean within dense ice. They feed on polar cod and squid. Walrus' are very vocal and gregarious.

There are many types of seals including the Bearded Seal, the Ribbon Seal and the Spotted Seal. But, one of the most popular breeds is the Harp Seal. They reproduce quickly because the females have pups every year. They feed on Arctic and polar cod, capelin, herring and krill.
