Final answer:
Plants capture solar energy through photosynthesis, and this energy is passed on to animals when they eat plants or other animals.
Step-by-step explanation:
Plants and many bacteria capture solar energy through photosynthesis. We release the energy stored in plants when we burn wood or plant products such as ethanol. We also use this energy to fuel our bodies by eating food that comes directly from plants or from animals that got their energy by eating plants.
