The Arctic ecosystem has a unique, complex food web that is fashioned by its distinctive plankton, animal species, and environmental factors. … The polar bear is the world’s largest land predator, and is found throughout the Arctic. Climate change is the main threat to polar bears today.
Is the Arctic a 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.
What are some ecosystems in the Arctic?
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.
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.
Why is the Arctic an important ecosystem?
The Arctic is crucial for lots of reasons. Not just because it’s home to the iconic polar bear, and four million people, but also because it helps keep our world’s climate in balance. … The Arctic also helps circulate the world’s ocean currents, moving cold and warm water around the globe.
What is the ecosystem of the Arctic fox?
HABITAT: Arctic foxes live in Arctic and alpine tundra, in coastal areas, on ice floes, and north of the tree line.
What type of ecosystem is the Arctic ocean?
The Arctic Ocean has the most extensive shelves of all oceans, covering about 50% of its total area. It comprises diverse ecosystems such as unique millennia-old ice shelves, multi-year sea ice, cold seeps and hot vents, and their associated communities.
What are decomposers in the Arctic?
The decomposers found in the Arctic tundra are bacteria, which are microorganisms, and fungi, which we previously mentioned as a member of the lichen partnership. Both bacteria and fungi work to break down dead and decaying matter, digesting and absorbing the nutrients in the process.
What is in the ecosystem?
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity. … A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.
What are four biotic elements of an Arctic ecosystem?
- Low shrubs such as sedges, reindeer mosses, liverworts, crustose and foliose lichen, grasses etc.
- Herbivores such as lemmings, voles, caribou, etc. …
- Migratory Birds are ravens, snow buntings, falcons, loons, etc.
- Insects such as mosquitoes, flies, moths, grasshoppers, etc.
What are the different types of ecosystem?
The different types of the ecosystem include:
- Terrestrial ecosystem.
- Forest ecosystem.
- Grassland ecosystem.
- Desert ecosystem.
- Tundra ecosystem.
- Freshwater ecosystem.
- Marine ecosystem.
Is Arctic a continent?
Although there are no penguins in the Arctic today, there are many fascinating connections between the polar north and our beloved, tuxedoed sweethearts of the south.
How does the Arctic ecosystem work together?
The Arctic ecosystem has a unique, complex food web that is fashioned by its distinctive plankton, animal species, and environmental factors. Carbon also cycles through the web from atmosphere to seawater and back. … Along the way, some carbon dioxide escapes back to the atmosphere through the organisms’ respiration.
What kind of ecosystem is the North Pole?
The North Pole is found in the Arctic Ocean, on constantly shifting pieces of sea ice.
How is climate change affecting the Arctic ecosystem?
Recent research shows that climate change can potentially alter the transport of pollution to polar areas and exert an even greater burden in the form of environmental toxins on the arctic ecosystem. As climate change warms arctic waters, higher temperatures can increase the uptake of toxins in marine organisms.
