LEFT SIDE RIGHT SIDE Energy Transformation takes places when energy changes from one form to another. Not all forms of energy are directly useful to organisms so they must be transformed into a useful form. Example In photosynthesis plants can’t store the sun’s light energy in their cells. The energy is transformed into chemical energy so it can be stored. Some energy in a transformation is lost to the environment as heat or sound. Some energy is released as heat during normal body functions such as digestion and movement. Energy released as heat helps the body maintain normal body temperature. During digestion food molecules are broken down, which releases the chemical energy stored in the bonds. Light energy and sound energy are transformed into electrical energy within an organism enabling it to sense its environment.
