depends on the habbitat, but generally they have similar conditions to that of the oragism they are pathogens to. eg staph aureus is an oppotunistic pathogen, and is found living on our skin.

Studies in a chimpanzee suggest that HCV may survive on environmental surfaces at room temperature at least 16 hours but not longer than 4 days. The potential for HCV to survive in the environment re-emphasizes the importance of cleaning and disinfecting.   http://www.hepc-connection.org/newsletter/01-03_04/stability.shtml\n\nHow long can HCV live outside the body and transmit infection? \nRecent studies suggest that HCV may survive on environmental surfaces at room temperature at least 16 hours, but no longer than 4 days.  http://www.hivandhepatitis.com/hep_c/hepc_bas.html#how2 and\nhttp://www.hivandhepatitis.com/hep_c/hepc_bas.html#how2

Many parasites can be found in the human respitatory system.  I'm talking worms and amoebas, not just bacteria and viruses.  Paragonium westermanni is a fluke that lives as an adult in the lungs.  Acanthamoeba sp. are Protozoic amoebas that can live in the lungs, as well.  Many nematodes (round, unsegmented worms) such as Ascaris lumbricoides, Necator americanus, Ancyclostoma duodenale, and Strongyloides stercoralis begin as eggs in the intestine, hatch into larvae, burrow through your intestine, into your blood stream, and enter your lungs where they are coughed up, swallowed, and return to the intestines where they live out their life cycles.  (That's a long way to go just to get to where you already are!)  While these guys are in the lungs they can produce pneumonia like symptoms.\n\nIf you want bacteria, some common causes of pneumonia and respiratory tract infections include:  Streptococcus pneumoniae, Neisseria sp, Haemophilus influenza and H. parainfluenza, and Klebsiella pneumonia, to name a few.\n\nYeasts include Candida albicans and Cryptococcus neoformans. \n\nThis list is incomplete at best.  Depending on your immune status and location, the occurences of these organisms vary.

ecosystem is used in a broader term to describe interactions between living organism and the environment in which they thrive. However habitat is concerned more about where these organisms live than the symbioses or interaction in their mist.\n\nHence we can talk about the human habitat, the animal habitat, the habitat of certain plants etc

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.

I'm not sure, but I'd imagine wet soil. The decomposers probably use the water to live and as means of digestion, seeing as water is an excellent solvent.

In biology, a host is an organism that harbors a virus, parasite, mutual partner, or commensal partner, typically providing nourishment and shelter.\n\nExamples: A cell can be host to a virus, a legume plant can be host to helpful nitrogen-fixing bacteria, an animal can be host to a parasitic worm, e.g. a nematode. \nA primary host or definitive host is a host in which the parasite grows mature; a secondary host or intermediate host is a host that harbors the parasite only for a short transition period. For trypanosomes, the cause of sleeping sickness, humans are the primary host, while the tsetse fly is the secondary host.\n\nThe host range or host specificity of a parasite is the collection of hosts that an organism can utilize as a partner. In the case of human parasites, the host range influences the epidemiology of the parasitism or disease. For instance, the production of antigenic shifts in Influenza A virus can result from pigs being infected with the virus from several different hosts (such as human and bird). This co-infection provides an opportunity for mixing of the viral genes between existing strains, thereby producing a new viral strain. An influenza vaccine produced against an existing viral strain might not be effective against this new strain, which then requires a new influenza vaccine to be prepared for the protection of the human population.\n\nThere are also reservoir hosts. These are vertebrates that host an infection while it isn't infecting humans and is used by the disease as a source of maintenance. a single reservoir host maybe be reinfected several times.\n\nIn parasitology, an intermediate host is an organism within which a parasite does not sexually reproduce. It may grow or reproduce asexually, but there is no exchange of genetic material between individuals. The host in which the parasite reproduces sexually is referred to as the definitive host. For example, the broad fish tapeworm Diphylobothrium latum develops in fish for part of its life cycle but only reproduces sexually when it is in a mammal digestive tract, so its intermediate host is the fish and its definitive host is the mammal.\n\nBecause the life cycles of many parasites are poorly understood, sometimes the "more important" organism is arbitrarily defined as definitive, and this designation may continue even after it is determined to be incorrect. For example, sludge worms are sometimes considered "intermediate hosts" for whirling disease, even though it is known that the parasite causing the disease reproduces sexually inside them

I don't think there is such a structure.  The basidia which bear the basidiospores are found on the gill surfaces.  I think the only thing separating them is space.

They've got the starring role! Bacteria, fungi, protists, all of them pick away at whatever dead matter they find, and the important thing is that they often secrete digestive enzymes onto the stuff so it breaks down. This helps them have small food particles to ingest, and it cleans up the environment to boot.

Any biological species or group of species whose function, population, or status can be used to determine ecosystem level or environmental integrity. An example of such a group of organisms is copepods and other small water crustaceans present in many water bodies.\n\nCopepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Many species are planktonic, but more are benthic, and some continental species may live in limno-terrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds and puddles, damp moss, or water-filled recesses (phytothelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Some copepods are parasitic and attach themselves to fish, sharks, marine mammals, and many kinds of invertebrates such as molluscs, tunicates, or corals.\n\nCopepods form a subclass belonging to the subphylum Crustacea (crustaceans). Some authors consider the copepods to be a full class. The group contains ten orders with some 14,000 described species. A scientist that studies copepods is a copepodologist.\n\nCopepods are very important food organisms for small fish, whales, and other crustaceans such as krill in the ocean and in fresh water. They are typically 1-2 mm long. They feed directly on phytoplankton, catching cells singly. Some scientists say they form the largest animal biomass on earth. They compete for this title with Antarctic krill (Euphausia superba).\n\nCopepods are sometimes found in the public mains water supply, especially systems where the water is not filtered, such as New York City and Boston, Massachusetts. This is not usually a problem in treated water supplies. In some tropical countries, such as Peru and Bangladesh, a correlation has been found between copepods and cholera in untreated water, because the cholera bacteria attach to the surfaces of planktonic animals. The risk of cholera from infected water can be reduced by filtering out the copepods (and other matter), for example with a cloth filter.\n\nMany species have neurons surrounded by myelin, which is very rare among invertebrates (other examples are some annelids and malacostracan crustaceans like palaemonid shrimp and penaeids). Even rarer is the fact that the myelin is highly organized, resembling the well-organized wrapping found in vertebrates (Gnathostomata).\n\nSome copepods are very evasive and can jump with extreme speed over a few millimeters (warning: takes some time to load to the correct speed):\n\n \nSlow-motion macrophotography video (50%) of juvenile Atlantic herring (38 mm) feeding on copepods - the fish approach from below and catch each copepod individually. In the middle of the image a copepod escapes successfully to the left.This scene was scanned with the ecoSCOPE, an underwater high speed microscope. Because clupeids (herrings) and copepods are both significant in terms of global biomass, this is the first record of what is one of the largest carbon flows of any animal food-chain transition in the oceans. It is a predator / prey relationship running at extreme speeds, with chances for both sides. Very little is known about the details, in spite of its importance for global processes, because copepods are difficult to keep in the laboratory and lose most of their escape capacity, and herring are very fast, alert and evasive organisms and flee normal camera systems or SCUBA divers. Oceanographers point out the importance of learning more about the influences of physical parameters, such as light, pollution or temperature, or the effects of hunting in a swarm. This copepod-herring relationship has implications for the fate of carbon in marine systems. If the copepod 'wins' (escapes), much carbon will sink with its fecal pellets into the depth of the oceans (see biological pump), sequestering carbon dioxide in the benthos. If the herring
