The Sun  is the ultimate source of energy for all living organisms.

• As we know, almost all food chain begins with a photosynthetic organism such as plants.
• In the process of photosynthesis, light from the Sun is the major component required for the breakdown of water and carbon dioxide into sugar and oxygen.
• Hence, the ultimate source through which energy is driven to each trophic level of an ecosystem is the Sun.
• Without the sun, plants will not be able to carry out photosynthesis and energy will not be produced.
