What is chemosynthesis?
Quick Answer
Chemosynthesis is the process by which some organisms make food using chemical energy instead of sunlight.
The Full Story
Chemosynthesis is especially important in deep-ocean environments where sunlight cannot reach. Certain bacteria and archaea use chemicals such as hydrogen sulfide or methane to produce organic compounds that support entire food webs. This process powers ecosystems around hydrothermal vents and cold seeps, where animals like giant tube worms depend on microbial partners. Chemosynthesis shows that life can thrive in environments very different from sunlit surface ecosystems.
Key Facts
1.Uses chemical energy rather than sunlight
2.Supports vent and seep ecosystems
3.Often involves bacteria and archaea
