How do microbes survive in deep sea hydrothermal vents? Green sulfur bacteria are unique among hydrothermal vent bacteria because they require both chemical energy (from hydrogen sulfide) and light energy to survive.
How do animals get food from hydrothermal vents? At deep hydrothermal vents, though, specialized bacteria can convert the sulfur compounds and heat into food and energy. As these bacteria multiply, they form thick mats on which animals can graze.
