che·mo·syn·the·sis

 (kē′mō-sĭn′thĭ-sĭs, kĕm′ō-)
n.
The synthesis of organic compounds by certain bacteria, especially in deep-sea hydrothermal vents, using energy obtained from the chemical oxidation of simple inorganic compounds. Chemosynthesis is thought to have been used by the first forms of life on Earth.

che·mo·syn·the·sis

(kē′mō-sĭn′thĭ-sĭs)
The formation of organic compounds using the energy released from chemical reactions instead of the energy of sunlight. Bacteria living in deep, dark areas of the ocean are able to survive by chemosynthesis. They use energy derived from the oxidation of inorganic chemicals, such as sulfur from deep volcanic vents, to make their food. Compare photosynthesis.
