Earth's primary producer of oxygen

WebMar 1, 2024 · The O2 on Earth was relatively scarce for much of our planet’s 4.6 billion-year existence. But at some point, Earth underwent what scientists call the Great Oxidation … While there are many abiotic sources and sinks for O2, the presence of the profuse concentration of free oxygen in modern Earth's atmosphere and ocean is attributed to O2 production from the biological process of oxygenic photosynthesis in conjunction with a biological sink known as the biological pump and a geologic process of carbon burial involving plate tectonics. Biology is the main driver of O2 flux on modern Earth, and the evolution of oxygenic photosynthesis by bacteria, …
