Meaning and Definition
The biological process by which certain organisms, typically bacteria, produce organic compounds (like carbohydrates) using energy derived from chemical reactions involving inorganic substances (e.g., hydrogen sulfide, ammonia), rather than from sunlight.
In a broader scientific or metaphorical sense, it can refer to any non-light-dependent synthesis of complex matter from simpler components.

FAQ
Frequently Asked Questions
No, chemosynthesis is performed by specific bacteria and archaea. Plants perform photosynthesis.
In extreme environments where sunlight cannot penetrate, such as deep-sea hydrothermal vents, cold seeps, and within some terrestrial rocks.
It is theorised that early life on Earth may have used chemosynthetic pathways before photosynthesis evolved, but this is not definitively proven.
Like photosynthesis, the end goal is the production of organic compounds (e.g., glucose) from carbon dioxide, but the energy source is chemical, not light.
The biological process by which certain organisms, typically bacteria, produce organic compounds (like carbohydrates) using energy derived from chemical reactions involving inorganic substances (e.
Chemosynthesis is usually technical / academic in register.
