What possible sources of energy may be used by microbes living in hydrothermal vents?

Question

Quizplus · Accepted Answer

Methane and sulfide are common sources of energy for microbes living in hydrothermal vents. Sulfide is typically produced by the vent fluids themselves or through the oxidation of sulfur compounds, while methane can be produced through a process known as methanogenesis. Nitrate and sulfate can also be used by some vent microbes, but they are typically less abundant than sulfide and methane.
