Which source-backed technical term is identified by this definition: "Formation of organic compounds using energy from inorganic chemical reactions without requiring light."? Features: chemical energy; no light requirement.

Answer options

• Option: Fermentation
  "Fermentation" vs. "Chemosynthesis" Fermentation denotes energy extraction; misses the target mapping. Fermentation remains in definition scope biological energy conversion. The task targets this mapping, so Fermentation remains wrong in this prompt. Fermentation belongs to the term family cellular energy process.
• Option: Photosynthesis
  "Photosynthesis" vs. "Chemosynthesis" Photosynthesis is a biological energy; misses the target mapping. Photosynthesis remains in definition scope biological energy conversion. The task targets this mapping, so Photosynthesis remains wrong in this prompt. Photosynthesis belongs to the term family cellular energy process.
• Option: Cellular respiration
  "Cellular respiration" vs. "Chemosynthesis" Cellular respiration describes energy; misses the target mapping. Cellular respiration remains in definition scope biological energy conversion. The task targets this mapping, so Cellular respiration remains wrong in this prompt. Cellular respiration belongs to the term family cellular energy process.
• Correct: Chemosynthesis
  "Chemosynthesis" - target Chemosynthesis uses chemical energy rather than light as the. Chemosynthesis remains in definition scope biological energy conversion. The task targets this mapping, and Chemosynthesis remains correct in this prompt. Chemosynthesis belongs to the term family cellular energy process.

Solution

Chemosynthesis

Chemosynthesis fits: the definition and features chemical energy; no light requirement distinguish the term in the biological energy conversion scope. The prompt targets Chemosynthesis, so the graph keeps this mapping stable against close alternatives. Source: Wikidata. As of: 2026-02-13.

Fun fact

Chemosynthesis carries the additional dataset detail biological energy conversion. The graph therefore uses a direct graph path.
