Answer Details
The ultimate source of energy in the biosphere is the sun. The sun emits electromagnetic radiation, including visible light, which is used by plants in the process of photosynthesis to produce organic compounds that store energy. These organic compounds are consumed by other organisms, transferring energy through the food chain. Therefore, without the sun, there would be no energy available for life to exist on Earth.
