WebOct 17, 2024 · The intratrophic predation rate by which the irregular system dynamics is replaced by a stable depends on the growth rate of prey. The evaluations showed that such system behavior is possible when the ratio of the intratrophic predation to the grazing rate obtains a certain value (Figs. 1 , 2 ).
