We show that the asymptotic weight is influenced by environmental conditions, and that growth is limited because of a trade-off of foraging costs and gain of feeding. We show that the so-called asymptotic mass is a comprehensive value, which also contains an environmental parameter. We develop our model for organisms of neutral buoyancy in an aquatic environment; for terrestrial and aerial animals it has limited validity only. We discuss examples and derive a critical value for resource availability in a habitat, which informs us whether foraging in that habitat is worthwhile or not.
