The ultimate source of energy for living things on Earth is the Sun. The Sun provides the energy that drives photosynthesis in plants, which in turn produces the oxygen and organic materials that support life. Mitochondria are responsible for cellular respiration and energy production within cells, but they rely on the energy stored in glucose, which ultimately comes from the Sun's energy.
