"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.

WebHydrogen sulfide chemosynthesis is a form of chemosynthesis which uses hydrogen sulfide. It is common in hydrothermal vent microbial communities Due to the lack of light in these environments this is predominant over photosynthesis. Giant tube worms use bacteria in their trophosome to fix carbon dioxide (using hydrogen sulfide as their energy source) … WebHydrothermal vents are chimney like structures on the ocean floor that release extremely hot, mineral rich water.

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. WebHow hydrothermal vents support life. In the ocean depths where no sunlight for photosynthesis can penetrate, marine life exploits hydrothermal vents as a source of energy. An EU-funded initiative investigated precisely how this is achieved.

WebScientists isolated species of Pyrolobus (“fire lobe”) and Pyrodictium (“fire network”) Archaea also from chimney walls. These heat-loving microbes (which grow optimally at temperatures above 100°C) get their energy from hydrogen gas and produce hydrogen sulfide from sulfur compounds from the vents. Hydrogen sulfide is highly toxic to ... WebHydrothermal vents revolutionized ideas about where and how life could exist. They raised questions that never entered our minds before.
