An FKD Feature exclusive. When our next president takes office in 2017, he or she will have a lot of preparatory work already underway.

Endothermic vs. Exothermic Reactions. An endothermic reaction occurs when energy is absorbed from the surroundings in the form of heat. Conversely, an exothermic reaction is one in which energy is released from the system into the surroundings. The terms are commonly used in the physical sciences and chemistry.
Photosynthesis is an interesting example of an endothermic reaction, because in this example the energy supplied to make the reaction go is not heat but light. The product (sugar) is an 'energy store' which the plant (or whatever eats the plant) can use later on to release the energy in respiration.
