No, bacteria are not considered autotrophs. Autotrophs are organisms that can produce their own food using sunlight or inorganic compounds as a source of energy. Bacteria are mainly classified as heterotrophs, as they obtain their energy by consuming organic matter produced by other organisms.
Examples of chemosynthetic organisms include certain types of bacteria, such as sulfur bacteria and methane bacteria, that can derive energy by oxidizing inorganic compounds like hydrogen sulfide or methane to produce organic molecules. These organisms are often found in extreme environments like deep-sea hydrothermal vents or certain cave systems where sunlight is not available for energy production through photosynthesis.
Organisms in the hadal zone typically rely on chemosynthesis rather than photosynthesis to make food. This process involves using chemical energy from sources like sulfur or methane to produce organic compounds. Some organisms may also capture food particles that fall from the surface waters above.
Combustion of sulfur produce sulfur oxides.
Sulfur
Vent organisms metabolize sulfur (or have a symbiotic relationship with organisms that metabolize sulfur).
Sulfur-oxidizing bacteria are considered chemoautotrophs because they obtain energy by oxidizing sulfur compounds (chemical energy source) and use this energy to fix carbon dioxide to produce organic molecules (carbon source).
It does not produce carbon dioxide or sulfur or nitrous oxides
Iceland's energy demands are met with geothermal heat. No fuel = No emissions = No sulfur dioxide
Burn Sulfur with oxygen and produce heat. In action, this is not really a good idea since the Sulfur will turn to SO2 upon combustion and in presence of humidity it will future react to sulfurous acid. Quite a health hazard form of fuel. Usually, we use Sulfur as reagent to produce Sulfuric and other stuff. We recover energy from reaction as byproduct.

When a matchstick is struck, sulfur dioxide is produced due to the combustion of sulfur-containing compounds found in the match head. This chemical reaction releases energy in the form of heat, which ignites the matchstick, allowing it to burn and produce a flame. The presence of sulfur in the match head contributes to the production of sulfur dioxide gas during this combustion process.
Combustion of sulfur produce sulfur oxides.
Archaebacteria are ancient prokaryotic organisms that can survive in extreme environments, while cyanobacteria are photosynthetic prokaryotes that produce oxygen as a byproduct of photosynthesis. Archaebacteria are more closely related to eukaryotes, while cyanobacteria are responsible for the oxygenation of Earth's early atmosphere.
