  • The main 2 sources of energy comes from the sun and Earth itself. The suns external drive undertakes a process in the atmosphere, hydrosphere, and earth itself. The suns energy is exchanged through photosynthesis and then goes through a process where an animal decomposes and returns the energy back to the earth where the cycle is repeated.
