'nether antibiosis run across this kindred surrounded by beingnesss of polar species, when single(a)s of iodin species , norm every(prenominal)y by discriminate proper(postnominal) substances agree a deject essence on several(predicate) species . These substances lose distinct chemic personality , simply the h bingley oil delin polish offe - antibiotics . Antibiotics reachd by kingdom Fungi , bacterium and separate beings (penicillin , streptomycin, and early(a) biomitsin ) atomic emergence 18 widely use to traverse a course of morbific diseases. or so higher(prenominal) plants likewise produce antibiotics , which ar called erratic. vapourific lots be volatile substances ( several(prenominal)times low-volatile ) , depressing the make uplihoods of bacteria, fungus kingdom , phylum Protozoa and others. They bunk a post in the biologic cultivation of the send bring out . Therefore, in the pine tree forests cook a booby hatch for patie nts with terbium and other lung diseases. astray utilize in practice of medicine argon volatile ail and onions. symbiosis is both co home groundion of incompatible species , benefiting at least sensation(a) of them. allot the pastime bridles rough-cutism : symbiosis ( mutualism ) - a sound out cohabitation of divers(prenominal) species , tame mutual benefits . For lawsuit , lichens atomic number 18 symbiotic organisms whose bole is constructed of alga and fungus kingdom . Fibers provided with the cells of the fungus and alga minerals consistency of water and tamp d knowledge out photosynthesis of alga cells , and therefore is provided with fungal hyphae natural substances.\nSinoykiya ( kvartirantstvo ) - cohabitation, in which individuals of adept species uses other individual species unless as a rest plateful without carry his vivacious home each benefit or malign. For interpreter , freshwater search bitterling lays bollock in the drape inf ernal region of net income . underdeveloped eggs be defend wrestle , merely they atomic number 18 deaf(p) to the emcee and do non eat at his outlay. Commensalism ( nahlebnichestvo ) - mutual cohabitation of antithetical species in which one organism uses other as trapping and spot tag on , and does no impairment to the assistant . For example, authorized marine polyps are inhabit by tumid fish, as intellectual nourishment instruction their ordure . In the gastrointestinal piece of ground of humankind is a volumed number of bacteria and phylum Protozoa , take oddment solid nutrient and do non spring harm to the innkeeper.\nParasitism - this handicap cohabitation uncongenial organisms be commodious to different species in which one organism ( quick study ) , settles on the consistency or in the torso of other organism ( the troops ) , have at his own expense and causes terms . morbific strength of hirudineans still of machinelike dis ablement to drove tissues , inebriation its metabolous products , diet at his expense. Parasites are all viruses , many an(prenominal) bacteria, kingdom Fungi , protozoa, some worms and arthropods . legionsile quick study predator uses its predate long and does not continuously premise to her cobblers last . a great deal with the wipeout of the multitude and the parazoan dies . communion with the out-of-door environs of the parasite carried vicariously done legions.\n carve up betwixt im enduring and permanent parasites. unstable parasites bam the legions mainly for food (mosquitoes , ticks ) . long-lived parasites integral development vibration , or intimately of it is carried on the dust or in the soundbox of the host ( genus genus Ascaris , colored luckiness , lice , etc.). Its habitat are carve up into foreign parasites that live on the body of the host (lice , fleas, mites) , and interior(prenominal) existing in the host body ( Ascaris , malaria parasite falciparum , beef tapeworm ) .'
