Oxygen is an aa released, maistly as a waste product. Maist plants, maist algae, an cyanobacteria perform the process o photosynthesis, an are cried photoautotrophs. Photosynthesis maintains atmospheric oxygen levels an supplies aw o the organic compoonds an maist o the energy necessary for ae life on Yird.
