WebAbout 21% of Earth’s atmosphere is oxygen, and most of the rest is nitrogen. But it hasn’t always been so. When life first arose (likely more than four billion years ago), there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow. WebMay 18, 2016 · Many prokaryotes are facultatively anaerobic. This means that they can switch between aerobic respiration and fermentation, depending on the availability of oxygen. Certain prokaryotes, like Clostridia bacteria, are obligate anaerobes. Obligate anaerobes live and grow in the absence of molecular oxygen.
