Is the sun is the ultimate source for energy on the Earth?
lana66690 [7]

Answer: The given statement is true.

Sun is the ultimate source for energy on the Earth. It is the natural and renewable source of energy on earth as it can easily be renewed and never run off. All living organisms which are present on earth are dependent on food for survival. For this, they become part of the food chain which provides them energy in the form of food. Food chain begins with plants as they are the primary producers in the food chain. They get energy for preparing food from sunlight in the form of light energy.

Moreover, the life forms which existed millions of years ago were dependent on sun for energy. The dead remains of these life forms have provided the non renewable sources of energy like fossil fuels on earth.

Thus, the sun is considered as the ultimate source of energy on the Earth.
