Because the sun gives of heat which keeps our muscles warm, which lets us use energy to do stuff. and all the other necesities..
Because almost all processes occurring on the surface of the earth rely on the sun as their ultimate source of energy. The only ones that don't are those that rely on geothermal energy.
Sun is the source of heat and light energy. It provides energy on earth's surface.
The energy of the sun comes from nuclear fusion occurring in the sun's core. The moon does not have an internal energy source. What little energy falls on it comes from the sun.
The sun is the most important energy source of all. Without the sun's energy heating the Earth's surface, there would be no potential for life. The sun is continuously radiating energy totaling 400 trillion trillion watts. Earth is ideally positioned in its distance from the sun so that the heat energy from the sun is not overbearingly hot, as on closer planets (Mercury, for example), and not too small to sustain temperatures that are suitable for life. The sun's energy can also be harnessed through the technology of solar cells, which convert the sun's energy (in photons) to usable electricity. Solar energy can power anything from a calculator to cars to entire buildings.
The Sun.
The Sun is the main and most important energy source.

sun is the energy source . We know that the primary produsers are plants, the source of photosynthesis is sun . Photosynthesis is giving food and energy to do all activities. Because sun is very very important to our planet earth.
An energy source is something that gives off energy. Such as sun, wind, water, coal. Sun is important in producing solar energy, wind is important for wind energy, Water for hydroelectric power And coal for thermal power.
Mainly, it is important for us, as our main energy source.
yes a sun is a source of energy
The energy from Sun is the most important.
the sun is the main source of energy of the earth the sun is the main source of energy of the earth the sun is the main source of energy of the earth
The primary is the sun
Because almost all processes occurring on the surface of the earth rely on the sun as their ultimate source of energy. The only ones that don't are those that rely on geothermal energy.
