Solar energy arrives and is converted into chemical energy by plants which is eaten by animals and converted again and the animal is either eaten by another animal or dies and is broken down by decomposers and the energy is converted back into basic elements for plants to feed off of with the help of solar energy hence the cycle starts again.The Sun is the major energy source for Earth. Geothermal energy is comparatively minor, since ice caps formed on the Earth's Poles where the average intensity of the Sun's radiation is low
