Definition:
 * geyser on the seafloor. It continuously spews super-hot, mineral-rich water that helps support a many different organism

Details:
 * Because of the depth sunlight cannot penetrate and allow plants to do photosynthesis. That's,why hydrothermal vents cannot be the basis of the food chain Animals at these depths depend on bacteria that are able to convert sulfur found in the vent's fluids into energy through chemosynthesis. Larger animals then eat the chemosynthetic bacteria or eat the animals that eat the bacteria

Even if it were, such activities would destroy this unique habitat.
 * <span style="background-color: #000000; color: #00ff00; font-family: 'Comic Sans MS',cursive; font-size: 140%;"> Bacteria discovered around these vents has already begun helping break down dangerous hydrogen sulfide waste from industrial processes, and treatment with sulfer-eating microbes is allowing gold to be extracted from some rocks more easily. Some scientists have suggested that life actually began millions of years ago around hydrothermal vents.
