On the early Earth, when atmospheric oxygen levels were 0.001% of those present today, dissolved Fe was thought to have been a lot more abundant in the oceans, and thus more bioavailable to microbial life. Iron sulfide may have provided the energy and surfaces for the first organisms. At this time, before the onset of oxygenic photosynthesis, primary production may have been dominated by photo-ferrotrophs, which would obtain energy from sunlight, and use t…
