what is the source of almost all energy on earth?\no earths hot core\no the sun\no stored carbon\no moving…

Brief Explanations:

The Sun is the primary source of energy on Earth. Through the process of photosynthesis, plants convert solar - energy into chemical energy. Fossil fuels are also formed from ancient plants and animals that originally got their energy from the Sun. Earth's hot core provides geothermal energy which is a small fraction compared to solar energy. Stored carbon and moving water ultimately get their energy from the Sun as well. For example, the water cycle is powered by the Sun's heat, and stored carbon in organisms and fossil fuels originally came from carbon - fixation during photosynthesis using solar energy.

Answer:

the Sun
