1. This process of obtaining energy from chemicals is known as chemosynthesis . 2. Instead, Tenebra's plants use chemosynthesis based on the transformation of sulphur oxides. 3. Lithotrophs that can produce sugars through chemosynthesis make up the base of some food chains. 4. It is this chemosynthesis that supports the complex communities that can be found around hydrothermal vents. 5. Chemosynthesis of bacteria provide the energy and organic matter for the whole food web in vent ecosystems.6. Many microorganisms in dark regions of the oceans also use chemosynthesis to produce biomass from single carbon molecules. 7. Bacteria are able to use reduced compounds from the vent effluent as an energy source ( chemosynthesis ). 8. Autotrophs are organisms that produce their own food ( production is greater than respiration ) by photosynthesis or chemosynthesis . 9. In these environments bacteria replace plants, through chemosynthesis , by transforming carbon molecules and nutrients into organic matter. 10. High concentrations of methane and sulfide in the fluids escaping from the seafloor are the principal energy sources for chemosynthesis .
