The seasonal cycles of plants, animals, detritus, and nutrients have been studied in Lake Erken in Sweden by Nauwerck and Pechlaner. The animal populations are heavier by weight than the algal populations by a factor of about five. Both investigators have suggested that the animals do not control the algal populations; Nauwerck suggests that the copepods, at least, subsist on bacteria and detritus. This paper attempts to show that the algae are controlled by the grazing animals and that the proportions by weight are those expected.
