In a food chain, which organisms convert sunlight into chemical energy?

• A. Producers (plants) via photosynthesis
• B. Consumers
• C. Decomposers
• D. Predators

Answer: (A)

Plants and other photosynthesizers capture sunlight and convert it into chemical energy through photosynthesis. Using chlorophyll, they turn light, water, and carbon dioxide into glucose (a chemical energy store) and oxygen. This stored energy in glucose becomes the fuel that plants use to grow, and it passes to other organisms when they eat the plants, anchoring the energy flow in the ecosystem. The other groups—consumers, decomposers, and predators—rely on the energy stored in producers rather than converting sunlight themselves, so they don’t directly transform light into chemical energy.
