the sun uses nuclear energy that is transformed into thermal and radiant energy. The radiant energy is
transformed by trees into chemical energy. Come of the chemical energy is stored into the tree’s fruit. We
eat the fruit transforming the chemical energy into mechanical energy and thermal energy.
