EVERYDAY SCIENCE

Detailed explanation-1: -The Sun is the planet’s primary source of light. Solar energy is trapped and used as a non-renewable source of energy to generate electricity on Earth. The sun’s solar energy is used up by plants during the photosynthesis process. As a byproduct of photosynthesis, oxygen is released into the atmosphere.

Detailed explanation-2: -The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Was this answer helpful?

Detailed explanation-3: -The sun is the ultimate source of almost all kinds of energy on earth, either directly or indirectly. Fossil fuels (coal, oil and gas) are the transformed forms of plants (and animals) which once lived on the earth and grew to capture the energy of the sun.

Detailed explanation-4: -The solar energy captured by the leaves is used to make food which is stored in the plant. All organisms are directly or indirectly dependent on plants for their food. Thus, the sun is the ultimate source of energy for all living organisms.

Detailed explanation-5: -The ultimate source of all energy is the sun. Plants get the energy to prepare their food from the sun and that is transferred to the whole food chain.
