What term would you give to this process? Energy of concentration? P. 125 6.2 Laws of Energy Flow in the Living World ____________ is freely convertible from one form to another, but ____________ can never be created or destroyed. Energy energy Systems that convert energy from one form to another are not 100% efficient, thus the amount of useful energy ____________. decreases In nature, as energy freely changes from one form to another, the total amount of energy ____________ ____________. Becomes useless? In living things, energy conversion is inefficient, with much energy being lost in the form of ____________. heat What form of energy do producers use when they set about to generate chemical energy— the energy of C―H and C―O―H bonds? Solar energy
