Abstract	Metabolism, and thus population dynamics, can be limited by energy, carbon, nitrogen, and/or other nutrients. This is due to homeostasis, the relatively constant composition of biomass. Yet growth-rate-dependent changes in the composition of biomass do exist. The dynamic energy budget (DEB) theory provides the framework to deal with these simultaneous limitations and stoichiometric restrictions. We illustrate the application with three examples. First, we discuss simple single-species growth of a chemolithoautotroph to illustrate the interactions between nutrients and substrates in growth. We show how the macrochemical reaction equation with variable yield coefficients can be decomposed in a number of subprocesses with constant yield coefficients. We then discuss a simple predator– prey system, where nutrients are accumulated in the prey, which no longer have a constant composition of biomass. The implication is a varying conversion efficiency from prey to predator, with consequences for qualitative aspec...
