Very few organisms can survive without sunlight or energy collected by other organisms from sunlight. Plants use the sun to make molecules from carbon dioxide and other basic chemicals. The energy stored in these molecules powers their metabolic activity and growth. Organisms that do not photosynthesize depend on plants for food and energy, so almost all life on Earth is dependent on the sun's energy. The basis of the food chain on Earth is photosynthesis.
