This note gives five applications of the eater-food interaction model (Gårding 2005) where cycle length is a function of the eater average birth rate defined as the inverse of average life span. The model extends to an analysis of predator-prey-food cycles (Gårding 2000). Here the cycle length is the same as that of en eater-food interaction whose average ’birth rate’ is the sum of the average birth rates of the predator-prey and prey-food interactions.
