Detailed explanation-1: -A new theory proposes the primordial life-forms that gave rise to all life on Earth left deep-sea vents because of their “invention” of a tiny pump. These primitive cellular pumps would have powered life-giving chemical reactions.
Detailed explanation-2: -The food chain at these ocean oases relies on a core process called chemosynthesis, which is carried out by bacteria. This is similar to photosynthesis used by plants on land, but instead of using light energy from the Sun, the bacteria use chemicals drawn from the vent fluid.
Detailed explanation-3: -Hydrogen sulfide is the primary energy source for hot vents and cold seeps. Chemosynthesis is a process special bacteria use to produce energy without using sunlight. The energy comes from the oxidization of dissolved chemicals which escape from the Earth’s crust through hydrothermal vents.
Detailed explanation-4: -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.
