What is Deinococcus radiodurans ecological niche?
375597
I dont know about its niche, but you could extrapolate from the following:\nDeinococcus has the remarkable ability to repair its genome from fragments. Scientists have completely fractured the genome, and in most organisms, this would kill the cell. However deinococcus can put its genome back together in the right order. weird isn't it. It can also grow at radiation high enough to melt glass. Its a crazy little bugger isn't it.

I can't remeber off the top of my head but there is a wonderful book out there called Bergey’s Manual of Determinative Bacteriology 9th Edition that should be able to answer this question for you.

Although often inconspicuous, fungi occur in every environment on Earth and play very important roles in most ecosystems. Along with bacteria, fungi are the major decomposers in most terrestrial (and some aquatic) ecosystems, and therefore play a critical role in biogeochemical cycles and in many food webs.\n\nMany fungi are important as partners in symbiotic relationships with other organisms, as mutualists, parasites, or commensalists, as well as in symbiotic relationships that do not fall neatly into any of these categories. One of the most critically important of these relationships are various types of mycorrhiza, which is a kind of mutualistic relationship between fungi and plants, in which the plant's roots are closely associated with fungal hyphae and other structures. The plant donates to the fungus sugars and other carbohydrates that it manufactures from photosynthesis, while the fungus donates water and mineral nutrients that the hyphal network is able to find much more efficiently than the plant roots alone can, particularly phosphorus. The fungi also protect against diseases and pathogens and provide other benefits to the plant. Recently, plants have been found to use mycorrhizas to deliver carbohydrates and other nutrients to other plants in the same community and in some cases can make plant species that would normally exclude each other able to coexist in the same plant community. Such mycorrhizal communities are called "common mycorrhizal networks". Over 90% of the plant species on Earth are dependent on mycorrhizae of one type or another in order to survive, and it is hypothesized that the presence of terrestrial fungi may have been necessary in order for the first plants to colonize land.\n\n\n\nIn soil, microorganisms which reside in the rhizosphere (a zone that includes the root surface and the soil that adheres to the root after gentle shaking) help in the transformation of molecular dinitrogen gas as their source of nitrogen, converting it to nitrogenous compounds in a process known as nitrogen fixation. This serves to provide an easily absorbable form of nitrogen for many plants, which cannot fix nitrogen themselves. Many other bacteria are found as symbionts in humans and other organisms. For example, the presence of the gut flora in the large intestine can help prevent the growth of potentially harmful microbes.\n\nThe ability of bacteria to degrade a variety of organic compounds is remarkable. Highly specialized groups of microorganisms play important roles in the mineralization of specific classes of organic compounds. For example, the decomposition of cellulose, which is one of the most abundant constituents of plant tissues, is mainly brought about by aerobic bacteria that belong to the genus Cytophaga. This ability has also been utilized by humans in industry, waste processing, and bioremediation. Bacteria capable of digesting the hydrocarbons in petroleum are often used to clean up oil spills. Some beaches in Prince William Sound were fertilized in an attempt to facilitate the growth of such bacteria after the infamous 1989 Exxon Valdez oil spill. These efforts were effective on beaches that were not too thickly covered in oil.\n\nBacteria, often in combination with yeasts and molds, are used in the preparation of fermented foods such as cheese, pickles, soy sauce, sauerkraut, vinegar, wine, and yogurt. Using biotechnology techniques, bacteria can be bioengineered for the production of therapeutic drugs, such as insulin, or for the bioremediation of toxic wastes.\n\n"Friendly bacteria" is a term used to refer to those bacteria that offer some benefit to human hosts, such as Lactobacillus species, which convert milk protein to lactic acid in the gut. The presence of such bacterial colonies also inhibits the growth of potentially pathogenic bacteria (usually through competitive exclusion). Other bacteria that are helpful inside the body are many strains of E. coli, which ar

The first three are correct.  I am having difficult finding an organism that is not somehow connected to an energy source.

They are unicellular organisms. They can be found at the end of the winter, when they are most numerous, in fresh water. They will cover surfaces of aquatic plants or poles and wooden borders of ponds. If you like to study them you can scrape the brown growth with a flat piece of plastic. You can also use a sponge.

Most members of that kingdom are unicellular, but some are colonial and there are some that a simple multicellular.\n\nVolvox is a green alga and makes its own food, so it is an autotroph.  Radiolaria are heterotrophs.

I would imagine something in the microbe department. Like a paramecium or ameba.

A Filipino biologist, Dr. Lina Villacarlos, recently discovered a new breed of parasitic fungus. She named it Entomorphthora leyteensis because it falls under the fungus family known as Entomorphthorales – a family that is classified as parasites on insect like the common housefly – and leyteensis from the name of the place where she discovered it, that is Leyte. \n\nEDWARD QUINTO A Luminous Vision : This Filipino biologist has worked tirelessly to make use of low-cost, local resources to help his country and people.\n\nEarly in the 1960's, Filipino biologist (Dioscoro) Rabor alerted the world that this magnificent bird was in serious danger of extinction. Eagles were found on only four of the 1,700 islands of the Philippine Archipelago. A handful of birds were reported on Leyte and Samar, with the majority on the islands of Luzor and Mindanao.\n\nCarmela Española, a Filipino wildlife biologist, found a group of these dark brown birds with their distinctive orange-red bills and legs foraging in the undergrowth near a stream while she was walking through a rainforest on May 11 this year.\nHer notes and photographs, along with the recordings of the bird’s loud, harsh, rasping calls, later helped determine that the species was not only new to her, but also new to science. Locals, however, know the bird by the name ‘piding’. Some residents said the birds were there sometimes even caught for food.\n\nWood describes how he was brought by Dr Alcala, a distinguished Filipino biologist, to the one island where the reef was expected to be safe, since a marine nature reserve had saved it from dynamiting. Only to find it swarming with illegal squatters, driven by hunger to invade, fish out and ruin the last reserve

Many archaea colonize extreme environments.\nThey include hyperthermophiles, sulfur-metabolizing thermo-\nphiles, extreme halophiles and methanogens. Because extrem-\nophilic microorganisms have unusual properties, they are a\npotentially valuable resource in the development of novel bio-\ntechnological processes. Despite extensive research, however,\nthere are few existing industrial applications of either archaeal\nbiomass or archaeal enzymes. \nCultivation methods, recent achievements in genomics, which are of key importance for the devel-\nopment of new biotechnological tools, and the application of\nwild-type biomasses, engineered microorganisms, enzymes\nand specific metabolites in particular bioprocesses of indus-\ntrial interest.\n\nA major limitation to the industrial application of archaeal en-\nzymes and metabolites is the low productivity of the fermenta-\ntion processes as a result of low growth rates and low biomass\nyields. To overcome these limitations, attention has been fo-\ncused on studying the physiology of archaea of biotechnological \ninterest and on designing bioreactors and bioprocesses that\nincrease productivity. Because of the unconventional environ-\nmental conditions needed for the cultivation of extremophiles,\ncontamination problems are minimal. Therefore, a continuous\nculture approach has been widely adopted.\n\nhttp://72.14.203.104/search?q=cache:ZMgRQbu0KPEJ:www.biotechinstitute.org/resources/pdf/yw14_2.pdf+applications+of+archaea+in+biotech&hl=en&gl=us&ct=clnk&cd=3&client=firefox-a  for more info

Cockroaches.  They can withstand nuclear radiation.

The answer is (D) the hawk.\n\nThe concept you are asking about is called biological magnification.  As energy flows through the food chain, there is significantly less energy available to each trophic level.  To accommodate, the organisms must eat a higher biomass from the trophic level below it.  Therefore, each level of the food chain accumulates higher amounts of DDT in their system.  Because the hawk is the third-order consumer in the example provided, it will have the highest concentration of DDT.\n\n<edited for spelling>

Under certain conditions, some one-celled organisms produce a protective form called a cyst that enables them to survive harsh environments.

E.\nBecause bacteria can obtain nutrition chemically, they can live in conditions that no-one thought possible, for example in volcanic vents at the bottom of the ocean.

The term you are looking for is "autotrophs."  The word means "self-feeders" and these types of organisms can synthesize their own energy-rich organic molecules.  They do not require any organic molecules from outside sources; only inorganic molecules.\nAutotrophs include plants and other photosynthetic organisms, and chemosynthetic bacteria (who form their food from chemicals).  \nAs a side note, heterotrophs are the organisms that cannot create their own food.\n\nHope this is helpful :-)

Maybe prokaryotes. But I'm not sure... I think there's still a debate about them cause they're not really living creatures... They are "alive" when they are inside a host, but otherwise, they're just lifeless proteins.. :)

Possible. By saying Life, I mean possibility of bacteria, microorganisms and other extremophiles. If we consider the extremophiles on earth, these bacteria are known to survive extreme habitats (thus the name). Extremophiles are found even in volcano springs and hot geiser. Scientists found extremophiles living and thriving in hot geisers in Yellowstone National Park and similar places. Usually we would think that such high temperatures would vapourize bacteria but NO...not all of them are same. There are certain microorganisms that live in extreme situations. \nThe water, ice sheets and geisers that scientists think are present in Enceladus, no matter how extreme, always has a possibility of life...atleast in Micro level. \nYour questions is well written with a tag question that explains what really you meant. Good you did that because when scientists talk about life elsewhere, people misinterpret it and think that scientists are talking about this green man with tentacles sticking out of his head. Thats not what scientists are talking about. Discovering even unicellular organisms or life of any sort in the universe other than earth is a big leap for human beings. That will give us a better picture of what we are and what our place in our solar system.
