Web4 feb. 2024 · Since there is no sunlight that deep, organisms can’t rely on photosynthesis to produce food. Instead, microbes around hydrothermal vents use a process called chemosynthesis, where they convert the chemicals inside the plumes into food. These bacteria, in turn, serve as food for other organisms that live on the vents. WebWith one important exception (hydrothermal vent systems, which we’ll explore below), almost all life today is powered by sunlight. Unlike other forms of electromagnetic radiation, sunlight has enough energy to drive the reactions of photosynthesis, but not so much energy that it would destroy molecules like protein or DNA (which is what ultraviolet or X …
