Definition of energy exchange

Energy exchange refers to the mutual flow of energy between ecosystems. The process by which the body obtains and releases energy from the external environment. The only form of energy that animals get is chemical energy, the energy contained in nutrients in the feed. The way to release energy is that cells use chemical energy to do work, produce products, and some of the energy is converted into heat to maintain body temperature and be lost to the external environment. Energy exchange obeys the first law of thermodynamics, that is, energy intake = work output + energy storage + heat dissipation. Depending on the situation, energy storage may release energy and exchange it with other forms of energy.
