The ecosystem of Antarctica has adapted to the harsh climatic conditions. These harsh conditions limit the complexity of the food web . On land, there are no trees or shrubs, and very few flowering plants. Mites and midges are at the bottom of the food chain (excluding the Antarctic sub-islands).
What is the name of the ecosystem in Antarctica?
The Antarctic realm is one of eight terrestrial biogeographic realms. The ecosystem includes Antarctica and several island groups in the southern Atlantic and Indian oceans.
Where are the ecosystems of Antarctica located?
The Antarctic region comprises the continent and surrounding sea south of the Antarctic Convergence, where cold Antarctic upper water sinks and mixes with warmer sub-Antarctic water. The continent, nearly centered on the South Geographic Pole, is isolated by the Southern Ocean from other land masses.
What type of environment is Antarctica and why?
Antarctica is a desert. It does not rain or snow a lot there. When it snows, the snow does not melt and builds up over many years to make large, thick sheets of ice, called ice sheets. Antarctica is made up of lots of ice in the form of glaciers, ice shelves and icebergs.
What is the Antarctic marine ecosystem?
The Antarctic ecosystem is unique in that the food chains are very short and often based on the availability of krill, which is vital for all animal life forms living in Antarctica.
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 ecosystems examples?
Examples of ecosystems are: agroecosystem, aquatic ecosystem, coral reef, desert, forest, human ecosystem, littoral zone, marine ecosystem, prairie, rainforest, savanna, steppe, taiga, tundra, urban ecosystem and others. plants, animals, soil organisms and climatic conditions.
What are Antarctic decomposers?
Bacteria, fungi and some worms all act as decomposers in this terrestrial environment, breaking down dead plants and animals in order to use their nutrients.
What is Antarctica biodiversity?
The Antarctic continent is isolated from the rest of the world by the Southern Ocean and successful natural colonization events are rare. As a result, terrestrial biodiversity is low and comprised of simple plants (e.g. mosses, lichens, liverworts) and animals (e.g. flies, mites and springtails).
What makes Antarctica extreme?
Antarctica is the windiest continent on earth. Winds flow down the coastal slopes under the influence of gravity. Speeds of these katabatic winds have been recorded up to 204 miles per hour (327 kilometers per hour).
What is the climate of Antarctica like?
Antarctica’s average annual temperature ranges from about −10 °C on the coast to −60 °C at the highest parts of the interior. Near the coast, the temperature can exceed +10 °C in summer and fall to below −40 °C in winter. Over the elevated inland, it can rise to about −30 °C in summer but fall below −80 °C in winter.
What would Antarctica be like without ice?
What would the Antarctic look like without ice? The weather will be fairly harsh even without the ice (six month “seasons” of summer sun and winter darkness), and Antarctica gets little precipitation, so will be quite dry and arid.
Does Antarctica have any natural resources?
There are deposits of minerals in Antarctica, including coal and iron ore. … Miners would have had to get through the thick ice sheet to reach the minerals. Antarctica is also a long way from world markets. Mined minerals would have had to be shipped over the treacherous Southern Ocean.
What types of plankton are in Antarctica?
Antarctic & Marine Plankton
- Ice algae and polar phytoplankton. We investigate environmental controls and impacts on ice algal/polar phytoplankton photosynthesis and productivity. …
- Effects of Ocean acidification and multiple ocean stressors on marine life. …
- Harmful algal blooms. …

- Antarctic krill.
What type of plants are in the Antarctic Ocean?
There are no trees or shrubs, and only two species of flowering plants are found: Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis).
What is the top of the food chain in Antarctica?
The top of the food web in Antarctica is the orca whale. Orca whales have no predators. They eat other whales, penguins and seals. Some of these seals, like the leopard seal, actually eat other types of seals.
