Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Mvura inokosha nokuda kwephotosynthesis nokufema. Masero anoita photosynthesis anoshandisa simba rezuva kuparadzanisa hydrogen iri mumvura neoksijeni. Hydrogen inosanganiswa neCO2 (inonyudzwa mumhepo kana mvura) kuti iite glucose uye inoburitsa okisijeni. Masero ose anorarama anoshandisa mafuta akadaro uye anoomesa hydrogen nekabhoni kuti abate simba rezuva uye anogadziridza mvura neCO2 mukuita (kufema kwemasero).  Mubvunzo: H2O inokosha pakuita chii?
