WebJan 20, 2012 · Yes, it is agent-based model. Every few milliseconds is a new move. On the field there are two types of creatures: predator and prey. The behavior of each of them is given by the following rules: Prey: 1) just moved to an unoccupied cell 2) Every few steps creates offspring to his old cell 3) Life expectancy is limited by the number of moves … Webas they are to predators and their prey. If the prey population limits the predator population, the system is referred to as bottom-up control. Vice versa, if the predator limits the prey population, then the system is referred to as top-down control. The idea that predators control prey (Hairston et al. 1960), or top-down control, has been
