Chemosynthetic bacteria are organisms that . Get energy from inorganic materials and convert them to organic compounds. Unlike plants, chemosynthetic bacteria . Get their energy through oxidation of inorganic substances rather than photosynthesis.
Chemosynthesis is the process of converting carbon (typically carbon dioxide or methane) into organic matter with the help of inorganic molecules (hydrogen or hydrogen sulphide) or methane as a fuel. The majority of energy is produced from sunlight via photosynthesis in plants.
