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.
Why sun is the source of energy?
The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. The sun heats the earth’s surface and the Earth heats the air above it, causing wind.
How can you say that sun is ultimate source of energy?
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 ultimate energy source?
The sun provides everything else. … All the energy embodied in fossil fuels and biomass is actually the sun’s energy stored as carbon. Each minute of every day, enough sunlight falls on the Earth’s surface to meet the world’s energy demand for an entire year; and it’s free.
Why is the sun the best source of energy?
It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
Do the sun is only source of energy for photosynthesis?
Sunlight is the source of energy for photosynthesis.
What are 3 forms of energy?
Potential energy is stored energy and the energy of position.
- Chemical energy is energy stored in the bonds of atoms and molecules. …
- Mechanical energy is energy stored in objects by tension. …
- Nuclear energy is energy stored in the nucleus of an atom—the energy that holds the nucleus together.
What is the source of all energy in the universe?

What are the two main sources of energy?
There are two sources of energy: renewable and nonrenewable energy.
What is the basic source of energy?
Primary sources can be used directly, as they appear in the natural environment: coal, oil, natural gas and wood, nuclear fuels (uranium), the sun, the wind, tides, mountain lakes, the rivers (from which hydroelectric energy can be obtained) and the Earth heat that supplies geothermal energy.
