Why Sun is considered the ultimate source of energy?

The Sun is the Ultimate Source of Energy. Every morning the sun rises, bringing light and heat to the earth, and every evening it sets. … Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.

Why sun is the ultimate source of energy?

Sun is the ultimate source of the because it provides energy in the form of light that helps the plants to make food and it is almost all the energies of the world that humans are also using . For example in Solar panels that helps in the work of the human .

Why is the sun ultimate source of energy Class 7?

Plants require sunlight, water, and CO2 for photosynthesis. Plants convert light energy from the sun into chemical energy which is in the form of food. Animals are heterotrophs and rely directly or indirectly on plants for food. … Hence sun called the ultimate source of energy.

How sun is the ultimate source of energy on the earth?

Answer: (1)

The sun is considered the primary energy source since it is the source of nearly all the earth’s energy. Plants produce food using sunlight, and the food we get from plants and animals also has its primary sunlight source.

What is the source of sun?

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.

Which is not a form of energy?

Temperature is a measure of how hot or cold an object is. It is the measurement of the intensity of heat energy present in a body. Therefore, it is not a form of energy, but a measure of the intensity of one. Hence, the correct option is C) Temperature.
