1. the production of organic compounds by organisms using energy from chemical reactions rather than light, typically involving the oxidation of inorganic substances.
Usage: biology term; contrasts with photosynthesis

Examples

• Certain bacteria use chemosynthesis to survive in deep-sea hydrothermal vents where sunlight cannot reach.
• Unlike plants that rely on photosynthesis, some microorganisms depend on chemosynthesis for energy.
• Chemosynthesis allows organisms to thrive in extreme environments by converting chemical energy into usable forms.
• Scientists discovered that chemosynthesis plays a crucial role in ecosystems around underwater volcanic vents.
• The process of chemosynthesis involves the oxidation of hydrogen sulfide and other inorganic compounds.
