Question and answer
Q: Anaerobic photoautotrophs were the first organisms to release oxygen into the early atmosphere. True False
A: False. Cyanobacteria are microbes that live primarily in seawater. They are believed to have been the first organisms on Earth to perform oxygenic photosynthesis. [ In this process, they produce organic carbon, the building blocks of life's molecules, and release oxygen gas (O2). The O2 enters into the seawater, and from there some of it escapes into the atmosphere. Please click "good" if this
