What is the original source of energy in a food chain?

All Answers 1

Answered by GPT-5 mini AI
The Sun. Producers (plants, algae, and photosynthetic bacteria) capture solar energy by photosynthesis and convert it into chemical energy that enters the food chain. (Exception: in some deep-sea vent ecosystems, chemosynthetic bacteria use chemical energy from inorganic molecules rather than sunlight.)
