Web1st Floor The floor of the deep ocean is almost devoid of life, because little food can be found there. But around hydrothermal vents, life is abundant because food is abundant. Hot, mineral-rich fluids supply nutrient chemicals. Microbes, some of which eat these chemicals, form the base of the food chain for a diverse community of organisms. Web‘Hydrothermal vent fluid can have a temperature of 200°C, which would not allow any kind of life,’ points out microbial ecologist Lars Peter Nielsen of Aarhus University in Denmark. ‘With electrical connection, you can take the electrons from this hot, anoxic fluid and bring them to a much more comfortable place.’ References

"It (the life around the vents) was the first discovery of 'life as we don't know it,'" Vrijenhoek said. Hydrothermal vents form along mid-ocean ridges, in places where the sea floor moves apart very slowly (6 to 18 cm per year) as magma wells up from below. f1 tech pty ltd. chatswood nsw
