Dynamic energy budget
Dynamic Energy Budget
Dynamic Energy Budget (pronunciation: dy·nam·ic en·er·gy bud·get, etymology: from the Greek dynamikos meaning powerful, and the Latin energia meaning activity or operation, and budget from the Old French bougette meaning little bag) refers to a comprehensive quantitative theory of how organisms use energy and nutrients to grow, reproduce, and maintain themselves.
The Dynamic Energy Budget theory is based on explicit assumptions about how organisms acquire and use energy and nutrients. These assumptions are translated into mathematical equations that describe the flow of energy and nutrients through the organism. The equations can be used to predict how changes in the environment or the organism's state will affect its growth, reproduction, and survival.
