sulfur
they obtain energy by hydrogen sulfide gas that flows from hydrothermal vents on the ocean floor.
Chemosynthetic organisms obtain their energy directly from raw chemicals in their environment. Examples of this include tubeworms living next to hydrothermal vents.
hydrothermal vents are on the bottom of the ocean where there is not much sunlight and is so deep, that they thought it would be impossible for any organisms to survive. apparently, hydrothermal vents provided heat and produced chemicals which bacteria feed on. And other animals feed on bacteria.
such organisms would be bacteria, fungi, protozoa, algae and other microorganisms mostly you would only need to find a rock and have a powerful microscope
No, not all living things need sunlight. It was recently discovered that there was a plethora of living organisms down in the deep parts of the ocean where no light can reach. These organisms were found, and presumed to be living off of, hydrothermal vents. For more info you should research hydrothermal vents.

chemical reactions
Chemosynthetic organisms obtain their energy directly from raw chemicals in their environment. Examples of this include tubeworms living next to hydrothermal vents.
Deep ocean hydrothermal vents are an extreme environment due to high temperature and pressure, toxic chemicals like hydrogen sulfide, and absence of sunlight. Organisms living near these vents have adapted to thrive in these harsh conditions by relying on chemosynthesis rather than photosynthesis for energy.

chemoautotrophssulfur
Special bacteria (chemosynthetic bacteria) live there which use the sulfur from the hydrothermal vents to make their own food. Other organisms, such as copepods (and other zooplankton), eat this bacteria. Other organisms, such as snails, shrimp, crabs, tube worms, and fish eat the copepods. Therefore, the number of organisms living in these vent systems are 10,000 times greater than areas in the ocean that do not have hydrothermal vents. These life forms would not be possible without the chemosynthetic bacteria, since sulfur is toxic to almost all other forms of life.

Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Vent organisms depend on chemosynthetic bacteria for food. The water from the hydrothermal vent is rich in dissolved minerals and supports a large population of chemoautotrophic bacteria.
The organisms living near hydro thermal vents are cold blooded animals whose body temperature does fluctuate as per the environment. There thermo regulatory receptors are missing and they do not posses any control over their body temperatures.
Bacteria. It uses the process called chemosynthesis to produce glucose.
