energy exists as light, heat, chemical energy , mechanical , and electrical energy. choose three of these five forms of energy. give an example of how a living organism might use each of the three types of energy you chose.

Chemical energy: plants use chemical energy when they convert the light into food (aka break it down into sugars)

Heat energy: Animals use heat energy so they wont freeze, by forming heat energy they will either be active (running, so on) or be somewhere that the sun hits them so that their bodies will convert the sunlight into heat

Electrical energy: Humans use electrical energy for just about everything like the lights, making food, using electronics, etc.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
