Life has traditionally been seen as driven by energy from the sun, but deep-sea organisms have no access to sunlight, so biological communities around hydrothermal vents must depend on nutrients found in the dusty chemical deposits and hydrothermal fluids in which they live. Previously, Benthic oceanographers assumed that vent organisms were dependent on marine snow, as deep-sea organisms are. This would leave them dependent on plant life and thus the sun. … WebApr 14, 2024 · Sulfidic ecosystems from thermal vents in deep sea, continental karst springs, and caves, are inhabited by some of the most extraordinary extremophile organisms on the planet 1,2,3.In these ...
