they use hydrotheral vents(thermal energy or heat energy)
it comes from sunlight

They oxidize inorganic compounds as a source of energy.ORChemoautotrophic bacteria uses energy produced by oxidizing or reducing chemical substances. The energy released from oxidation or reduction is used to synthesize organic compounds. Hence they don't need sunlight.This chemosynthesis does not and this is how it differs from photosynthesis.
Chemoautotrophs
The source of energy that is used in chemosynthesis is the chemicals.
Because there is no sunlight down there, so they have to rely on chemosynthesis

they get their energy by chemosynthesis: metabolising the sulfur in hot springs Source: my textbook:D
The Source of energy for photosynthesis is sunlight.
chemosynthesis is the process by which an organism forms carbohydrates using chemicals rather than light, as an energy source and photosynthesis is the process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as energy source.
Sunlight IS a source of energy. It has its drawbacks - like not being available during night - but it's definitely energy.
They get their energy from sunlight.
The source of energy of plants is sunlight.
It is the energy source. It is using as the energy source.
