Carbon fixation
Carbon fixation is how gaseous carbon dioxide is converted into a solid compound. It occurs in autotrophs during the Calvin cycle and in some heterotrophs.
Carbon Fixation Media
Cyanobacteria such as these carry out photosynthesis. Their emergence foreshadowed the evolution of many photosynthetic plants and oxygenated Earth's atmosphere.
