Carbon Cycle. Misimboti uye kukosha

Mune biosphere yedu pane zvakawanda pezvakaitwa zvakaoma anokonzerwa rinokosha rinoitwa zvipenyu, matambudziko kuchinja kwevanhu uye shanduka kuitika mudumbu pakukora uye mukudzika munyanza. The chikuru ndiye kabhoni yatinofema. Pasina izvozvo, upenyu Panyika.

Kazhinji, riparadzirwe kabhoni iri yose mashandiro anokonzera uptake uye excretion mumhepo pamusoro carbon dioxide. Kuitwa pakati kabhoni isu tese sezvo photosynthesis, uye vane basa chikamu ichi chirimwa. Sarudza / kudzoka carbon dioxide inobvisa kunoitika kuburikidza naye nedzinovengwa zvipenyu, basa maindasitiri mabhizimisi uye manyowa pezvakaitwa

Zano carbon kutenderera zvichava zvakazara kumirira kwacho rine muzvikamu zviviri:

• The kuitwa kuti carbon dioxide inobvisa (CO ₂₎ zvinomera, nemaziso zvipenyu kwaizotevera kushanduka yawo yakawanda kunzwisisa zvinhu makemikari (mafuta, makabhohaidhiretsi, mapurotini).
• Kudzoka carbon dioxide inobvisa mumhepo kuburikidza afemeruke zvipenyu, uye mune dzimwe nzira.

Zvisinei, carbon kutenderera zvikuru kuoma muitiro. Saka, pashure pokufa zvipenyu, vamwe vavo vari kupatsanurwa nemabhakitiriya uye chaizvoizvo akadzokera mumhepo pfupi yenguva. Asi chikamu zvisaririra dzikwanise vakafa makemikari nyaya.

Ndiyo zvasara makemikari nyaya mashomanana zana nemakore achaparadzwa mudzoke, uye pakupedzisira dzikava marasha, mafuta uye peat. zvicherwa aya anoshandiswa zvinangwa zvakasiyana-siyana nevanhu uye kabhoni pavo achava akadzokera mumhepo.

Yoga vanoda kugara vari CO ₂ kupora kwacho kabhoni yatinofema.

Kwemafuta. Lipolysis dzakasiyana mavambo runobvira nokuda kuitawo izvi tusingaoneki vane enzayemu yakatungamirira cleavage kuti akakura ichi. Izvi zvinoguma glycerol uye yakakwirira mafuta acids dzakatevedzana. Glycerol uchiora mu pyruvic asidhi (PVK). Zviri, zvichienderana nezvirango, chobva mvura, asidhi kana doro uye kabhoni Morekuru mudenga achapiwa pachena.

Makabhohaidhiretsi. Izvi zvinhu ndiwo Vatakuri chikuru faibha iyo vawana uye kupatsanurwa chete nevamwe tusingaoneki. Nokufamba ayo kubudiswa kuumbwa shuga iri oxidized zvinenge mhando dzose notumwe noutachiona. Somugumisiro, shuga iri rwakakamukana mvura uye carbon dioxide. Izvi - kwete chete kuzvipedza. The oxidation kwacho kungaita kuti paumbwe methane, asi kusunungura kabhoni dzinosungirwa.

Nokuti vose pezvakaitwa havasi zvakakura mashoko kuyerera ayo, muri mhando mbiri riparadzirwe zvinhu zviri biosphere:

• Geological (inotungamirwa chicherwa zviwanikwa) - ungatosvika nezviuru uye mamiriyoni emakore.
• Biological (rufu uye manyowa zvinomera nemhuka) - chaizvo muitiro kuti anogona kutora pose kubva pamazuva akawanda kune akawanda.

Chokwadi, tsananguro anoratidzwa pano zvachero chaizvo uye hazviratidzi musimboti kwemakemikari nemamwe maitiro ayo nyika rinotsigirwa nezvinoitwa kabhoni yatinofema.
