Much more interesting than I thought it would be. The iron and sulphur makes me think about the amount of energy those elements provide to form reactions that sustain life(scroll down for pictures), and how differing amounts of those elements may influence the colonization.
I’m also reminded of the sea monster at the bottom of the carbon food chain where there’s little oxygen and energy is scarce.
To the other extreme where oxygen is rich and where historically moisture rich microbes respire excess carbon from soils.
