EVERYDAY SCIENCE

Detailed explanation-1: -Sunlight is essential for photosynthesis. Sunlight provides energy for the reaction between carbon dioxide and water to produce glucose and oxygen. Hence solar energy is considered as the ultimate source of energy.

Detailed explanation-2: -The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

Detailed explanation-3: -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.

Detailed explanation-4: -On Earth, the main source of natural light is the Sun. The Sun makes its light when atoms smash together inside it, releasing huge amounts of energy. It fires off the energy into space in all directions. Some of the radiation travels to Earth as the light and heat we know as sunlight.

Detailed explanation-5: -Solar radiation, often called the solar resource or just sunlight, is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies.
