Some of the energy becomes locked in them, in the form of _____________ energy. Over many years, loads and loads of plants grew. Some were ______________ underground. Their energy became trapped as they were turned into _______________. _____________ that fed on the plants fell to the bottom of the ________. They were buried under ____________ and chemical changes occurred to make ____________ and ______________. We call fuels formed from living things in this way ______________ fuels.
