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.
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?

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.
Where on Earth can microbes not grow?
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.
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.

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 countries are in Antarctica?
There are no countries in Antarctica, although seven nations claim different parts of it: New Zealand, Australia, France, Norway, the United Kingdom, Chile, and Argentina. The Antarctic also includes island territories within the Antarctic Convergence.
Is a virus a microorganism?
Technically a microorganism or microbe is an organism that is microscopic. The study of microorganisms is called microbiology. Microorganisms can be bacteria, fungi, archaea or protists. The term microorganisms does not include viruses and prions, which are generally classified as non-living.

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.
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.
Where on Earth does life not exist?
The Dallol ponds actually prevent life from forming because they contain chemical barriers like chaotropic magnesium salts that help break down hydrogen. Combined with the salty, acidic and hot environment, life receives no encouragement in the pools.
Is there a place on Earth where there is no life?
The hot, hyperacid ponds of Dallol Geothermal Field in Ethiopia are devoid of any form of life, and this finding could help us understand the limits of habitability of life on Earth despite the presence of liquid water.
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.
