Ultimately, there is basically ONE source of energy - the energy we get from the Sun.

the first sources of heat was asteroids and meteorites. another sources of heat for the early earth was the contraction of gravity. the third sources of energy for the early earth was radioactivity. hope this helped :)
The Earth has two sources of energy, the sun's radiation and heat from inside the Earth. The sun is most important and life could hardly exist except at a very primitive level without it.
Point out that both processes use energy to produce carbohydrates-energy-rich compounds that organisms can use to power life processes. Energy in Biological Systems Students may think that energy is formed, or created, by the processes of photosynthesis or chemosynthesis.
All the energy for living things and all the energy for fossil fuel, hydroelectric and wind energy comes form the energy of sunlight. Without sunlight there would be no life and Earth would be a frozen dead planet.
Sunlight is the main energy source for life on earth.
The sun Solar energy is the primary source of energy on earth. Solar energy is the basis of the vast majority of life on earth via the production of carbohydrates by plants which is consumed directly or indirect by other forms of life. the other of energy for life being from deep ocean vents utilized by chemotrophic bacteria.
it is the sun
The energy from the Sun, solar energy drives all the process important to life on Earth.
Ultimately, sunshine is the energy source for most life.
