Correct Answer: 0.1 per cent
Solution : The correct answer is 0.1%
Plants in a food chain use just around 0.1% of the solar energy that reaches Earth. This is due to the inefficiency of photosynthesis, the process through which plants turn sunlight into energy. Plants also use part of the energy they generate to support their own life activities, such as growth and reproduction. The remainder of the solar energy is lost to the atmosphere or reflected back into space.
