Summary
[edit]DescriptionCicle de l'oxigen.svg |
Català: L’H2O cau en forma de precipitació al mar i a la terra i és rebuda per les plantes i els animals. Una part de l'aigua restant dipositada s'evapora de manera que torna a condensar-se formant núvols. Una altra part de l'aigua dipositada en terra es filtra cap a l'interior de la terra o s'escorra per torrents i rius.
El fitoplàncton, les plantes i els arbres a través de la fotosíntesi, incorporen CO2 i alliberen O2 a l'atmosfera. A través de la respiració, els animals expulsen CO2 alhora que incorporen O2. Les indústries i les erupcions volcàniques es sumen a l'expulsió de CO2. Il·lustració vectorial realitzada amb l'assessorament de Mercè Piqueras, biòloga
