Bacteria genera found in both air samples and the Antarctic include Staphylococcus, Bacillus, Corynebacterium, Micrococcus, Streptococcus, Neisseria, and Pseudomonas. Bacteria were also found living in the cold and dark in a lake buried a half-mile deep (0.80 km) under the ice in Antarctica.
Is there microbial life in Antarctica?
Chilean Antarctic survey finds dramatic variety of organisms adapted to unusual conditions. You might not expect bacteria living in Antarctic ice to be well suited to life in a boiling kettle, but that is what Chilean scientists discovered during an expedition last year.
What kind of bacteria is in the Arctic?
In the Arctic Ocean, planktonic Chloroflexi bacteria recently acquired genes used for degrading carbon from land-based Actinobacteria species. As melt-swollen Arctic rivers carried sediments from thawing permafrost to the sea, the genes for processing permafrost carbon were also transported.
Does Antarctica have fungi?
There are about 20 species of macro-fungi mushrooms that have been reported to exist in the Antarctic. In addition, there are about 100 species of mosses, 25 species of liverworts and upwards of 400 species of lichen. … Amsler Island, where the mushrooms were found, is glimpsed behind a collapsed snow bridge.
What organisms is not found in Antarctica?
Antarctica, including the subantarctic islands, has no natural fully terrestrial mammals, reptiles, or amphibians. Human activity has however led to the introduction in some areas of foreign species, such as rats, mice, chickens, rabbits, cats, pigs, sheep, cattle, reindeer, and various fish.
Does Antarctica have any dirt?
Antarctica is a continent, which means it’s made out of land, not just ice. The areas that are covered in ice still have soil underneath all of that ice. … But, there’s still soil under there! The areas that do not have ice allow you to see the soil directly, without drilling through any ice.
Where on Earth are there no microbes?
Living beings, especially microorganisms, have a surprising ability to adapt to the most extreme environments on Earth, but there are still places where they cannot live. European researchers have confirmed the absence of microbial life in hot, saline, hyperacid ponds in the Dallol geothermal field in Ethiopia.
Does Antarctica have fertile soil?
The soils on inland peaks in Antarctica are virtually sterile (lifeless) and the soil in some of the dry coastal areas hosts only the most simple microscopic organisms. The only richly organic soils to be found on Antarctica are in penguin colonies where the penguin droppings mix with the soil.
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.
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.
Are bacteria found in the Arctic snow?
Bacteria are hardy little creatures, but even they have their limits. One of those was previously thought to be polar ice and snow, but a new study from the University of York has now directly observed bacteria living in those conditions in both the Arctic and Antarctic regions.
Where are microorganisms found?
Microbes are tiny living things that are found all around us and are too small to be seen by the naked eye. They live in water, soil, and in the air. The human body is home to millions of these microbes too, also called microorganisms. Some microbes make us sick, others are important for our health.
What are 5 facts about Antarctica?

- There is no Antarctic time zone. …
- Every way is north! …
- Antarctica has active volcanoes.
How does fungi survive in Antarctica?
Thus, some fungi may survive in Arctic and Antarctic environments by avoiding the extreme low temperatures during winter through annual germination from airspora during spring and summer. There is evidence, however, from air samples of marked seasonality in spore dispersal.
What do Antarctic silverfish eat?
The Antarctic silverfish is a species that eats krill and is the prey of many larger species in the Antarctic food web such as seals, baleen whales (e.g. humpbacks), sea birds (e.g. snow petrel), toothed whales (e.g. orca) and penguins (e.g. Adelie penguin).
Why can't spiders live in Antarctica?
Cold water can hold more dissolved oxygen than warm water, and the oxygen content of seawater near the coast of Antarctica is especially high. … So far their results seem to support the oxygen hypothesis for polar gigantism: larger sea spiders fare poorly in low oxygen water.
What is the biggest animal in Antarctica?
The largest land animal in Antarctica is a wingless midge, Belgica antarctica, which is less than 1.3 cm long. All the other, larger, animals in Antarctica are considered marine animals, meaning that they feed and live largely in the ocean.
Does Antarctica have a flag?
True South is the only flag of Antarctica formally recognized by members of the Antarctic Treaty System, the condominium that governs the continent. However, adoption of the flag is not yet universal, and dozens of unofficial designs have also been proposed.
Is there any grass in Antarctica?
Antarctic hair grass (Deschamsia antarctica) grows primarily in the Antarctic Peninsula in small, concentrated tufts throughout rocky areas. These plants are most commonly seen amongst penguin colonies, and can withstand high amounts of disturbance without withering away.
Do polar bears live in Antarctica?
Polar bears live in the Arctic, but not Antarctica. Down south in Antarctica you’ll find penguins, seals, whales and all kinds of seabirds, but never polar bears. Even though the north and south polar regions both have lots of snow and ice, polar bears stick to the north. … Polar bears don’t live in Antarctica.
Where is the most lifeless place on Earth?
The climate of the Atacama Desert limits the number of animals living permanently in this extreme ecosystem. Some parts of the desert are so arid, no plant or animal life can survive.
What is the most lifeless place on Earth?
- Dallol is a terrestrial hydrothermal system located in the east-African country of Ethiopia.
- The wider Dallol area is one of the hottest and driest places on Earth.
Is there a place on Earth without water?
In the Atacama Desert in northern Chile, it looks as if nothing could ever survive. It is one of the driest places in the world, and some sections of the Mars-like expanse can go 50 years without feeling a drop of rain.
Is there Airport in Antarctica?
Antarctica has 20 airports, but there are no developed public-access airports or landing facilities.
Is there land under the ice in Antarctica?
Some areas (2% in fact) of Antarctica are ice free, so it is very easy to see that there is land present. However, in other places, the Antarctic Ice Sheet is thousands of meters thick. Scientists therefore need to look underneath the ice to map the land.
How cold is Antarctica?
By far the coldest continent, Antarctica has winter temperatures that range from −128.6 °F (−89.2 °C), the world’s lowest recorded temperature, measured at Vostok Station (Russia) on July 21, 1983, on the high inland ice sheet to −76 °F (−60 °C) near sea level.
Are there any churches in Antarctica?
There are eight churches on Antarctica proper, with another two located south of the Antarctic Convergence. The southernmost of these religious buildings is the Chapel of Our Lady of the Snows, a Catholic chapel carved out of the ice surrounding the Belgrano II Base, at Bertrab Nunatak.
Is there an oasis in Antarctica?
In Antarctica there are, in addition to mountain tops and nunataks, other natural snow- and ice-free areas often referred to as “Antarctic oasis” or “dry valleys”. These areas are surrounded by the Antarctic ice sheet or in coastal areas situated between the ice sheet and the Antarctic ice shelves.
What animals do you associate with Antarctica?
Antarctic animals – The most abundant and best known animals from the southern continent, penguins, whales seals, albatrosses, other seabirds and a range of invertebrates you may have not heard of such as krill which form the basis of the Antarctic food web.
What are some decomposers in Antarctica?
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 the Arctic 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 is a herbivore that lives in the Arctic?
The characteristic large herbivores of the Arctic tundra are the reindeer (Rangifer tarandus) of Eurasia and North America (where they are known as caribou) and the musk ox (Ovibos moschatus) of Greenland and some Canadian Arctic islands.

The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below.
Why are microorganisms so called?
These observations show that water and soil are full of tiny organisms, though not all of them fall into the category of microbes. These microorganisms or microbes are so small in size that they cannot be seen with the unaided eye. … That is why these are called microorganisms or microbes.
Why is it cold in Antarctica for kids?
Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn’t come up at all for months at a time. … The Arctic is ocean surrounded by land.
Why is Antarctica dark?
Antarctica has six months of daylight in its summer and six months of darkness in its winter. The seasons are caused by the tilt of Earth’s axis in relation to the sun. The direction of the tilt never changes. … In the winter, Antarctica is on the side of Earth tilted away from the sun, causing the continent to be dark.
Why does nobody live in Antarctica?
Due to its remoteness, inhospitable weather conditions and lack of natural land bridges connecting it to other continents, Antarctica has spent the last 35 million years in relative silence and seclusion.
