Numerical studies are made on the complex behavior of a cellular automaton whichserves as a phenornenological model for an ecosystem. The ecosystem is assumed tocontain only three populations, i.e., a population of plants, of herbivores, and of carnivores. A two-dimensional region where organisms live is divided into square cellsand the population density in each cell is regarded as a discrete variable. The influenceof the physical environment and the interactions between organisms are reduced to asimple rule of cellular automaton evolution. It is found that the time dependentspatial distribution of organisms is, in general, very random and complex. However,under certain conditions, the self-organization of ordered patterns such as rotatingspirals or concentric circles takes place. The relevance of the cellular automaton as amodel for the ecosystem is discussed.ecosystem, cellular automaton, self-organizing pattern, computer experiment
