1.They trade away higher fecundity for future reproduction. 2.Resources devoted to one function or trait cannot be devoted to another. For all organisms,natural selection favors allocation strategies that optimize resource use over the life course. Because energy and resources are inherently limited,all organisms face important trade-offs in how they divide and use their resources at any given point in the life course.The laws of thermodynamics dictate that energy allocated for one task cannot simultaneously be allocated for another task.
