Ndipei pfupiso yemutsetse mumwe chete pamusoro pekunyungudutsa
Context:Kunyungudutsa muitiro wokushandisa kupisa kune chicherwa, kuti ubvise simbi isiri yesimbi. Chimiro chokushanda nesimbi. Inoshandiswa kubvisa simbi dzakawanda kubva mumarasha adzo, kusanganisira sirivha, simbi, mhangura, nedzimwe simbi dzisina kusimba. Kunyungudutsa kunoshandisa kupisa uye chinoderedza makemikoro kuora chicherwa, kuchidzinga zvimwe zvinhu semagasi kana kuti tsvina uye kusiya simbi yapasi. Mudziviriri wekuderedza kazhinji kazhinji inopa mafuta emagetsi e carbon, yakadai sekokisi<unk>kana, munguva dzekare, marasha. Oxygen iri mu ore inosunga kune carbon pamhepo yakanyanya sezvo simba remagetsi emakemikari ezvisungo mu carbon dioxide (CO2) rakaderera pane zvisungo mu ore.
Kunyungudutsa muitiro wokubvisa nesimbi kubva ores dzavo nokushandisa kupisa uye makemikari-kuderedza mumiririri kudzinga kure vasingadiwi zvinhu sezvo magasi uye kusiya chawo (zvaidiwa) zvinhu shure.
