The correct answer is Sun.

Key Points

  • The sun is considered the ultimate source of energy.
  • Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis.
  • Hence the food we get from plants and animals also has its primary sunlight source.
  • Every day, the sun radiates (sends out) an enormous amount of energy.
  • It radiates more energy each day than the world uses in one year.
  • Solar energy is a renewable energy source.
  • The sun’s energy comes from within the sun itself.
  • Like most stars, the sun is made up mostly of hydrogen and helium atoms in a plasma state.
  • The sun generates energy from a process called nuclear fusion

Additional Information

  • Resources that are drawn from nature and used without much modification are called natural resources.
  • Natural resources can be divided into renewable and non-renewable resources.
  • Renewable resources are those which get renewed naturally over time.
    • Examples of renewable resources are:
      • The sun.
      • Wind.
      • Wildlife
      • Fisheries.
      • Hydropower(water).
      • Geothermal power.
  • Renewable resources like solar and wind energy are unlimited and are not affected by human activities.
  • Water seems to be an unlimited renewable resource yet careless use of water, soil, and forest can affect their stock.
