The Arctic consists of taiga (or boreal forest) and tundra biomes, which also dominate very high elevations, even in the tropics. Sensitive ecosystems exist throughout the Arctic region, which are being impacted dramatically by global warming.
Is the Arctic Circle an ecosystem?
The Arctic is a unique ecosystem with a complex food web made up of organisms adapted to its extreme conditions. It is one of the most biologically productive ecosystems in the world, supporting many large fisheries and huge populations of migratory birds that come to the Arctic in the summer to breed.
Is the Arctic ecosystem aquatic or terrestrial?
One fifth of the total coastline of the world, or about 177,000 km, occurs in the Arctic, a biome that comprises only about 5% of the Earth’s terrestrial surface.
Where is the Arctic ecosystem found?
The Arctic is dominated by the Arctic Ocean basin, and the icy reaches of Scandinavia, Russia, the U.S. state of Alaska, Canada, and Greenland. The Arctic is the northernmost region of Earth. Most scientists define the Arctic as the area within the Arctic Circle, a line of latitude about 66.5° north of the Equator.
What are the ecosystems?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. … Abiotic factors include rocks, temperature, and humidity.
What are the ecosystems in the Arctic tundra?
Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.
What is one ecosystem services provided by the Arctic marine ecosystem?
Reindeer herding; commercial fisheries; commercial and subsistence hunting, gathering, and small-scale fishing; and recreational and sport hunting and fishing are the provisioning services addressed here. These are the main sources of food produced in the Arctic.
What are the different types of terrestrial ecosystem?
While there have been many classification schemes developed over time, it is now generally accepted that there are six types of terrestrial ecosystems. These include taiga, tundra, deciduous forest, grasslands, tropical rain forests, and deserts. Taigas are cold-climate forests found in the northern latitudes.
What continent is Arctic?
These include the polar bear (as much a marine as a terrestrial animal), caribou, arctic wolf, arctic fox, arctic weasel, arctic hare, brown and collared lemmings, ptarmigan, gyrfalcon, and snowy owl.
What kind of ecosystem is the North Pole?
The North Pole is found in the Arctic Ocean, on constantly shifting pieces of sea ice.
What are the 4 types of ecosystems?
The four ecosystem types are classifications known as artificial, terrestrial, lentic and lotic. Ecosystems are parts of biomes, which are climatic systems of life and organisms. In the biome’s ecosystems, there are living and nonliving environmental factors known as biotic and abiotic.
What are examples of diverse ecosystem?

- Large marine ecosystems.
- Marine ecosystems.
- Old-growth forests.
- Coral reefs.
