Population dynamics depend on the growth and reproduction of individuals, which are dictated by energy intake and budgeting. Here we show how to construct a simple matrix population model from a dynamic energy budget model in a constant or seasonally variable environment. The matrix model accurately predicts asymptotic population dynamics for a wide range of parameter values and environmental conditions. The model captures some transients well, but more elaborate stage structure is necessary when the initial age distribution within stages is far from the stable age distribution.
