Abstract:A food chain describes predator-prey interaction between species. Since behaviors of some species in the food chain have an effect on the whole ecosystem, it is very important to consider temporal-spatio change of the population of species from the view point of maintenance, management, protection of the ecosystem. In this paper, we consider the food chain consisting of three populations, fish, zooplankton and phytoplankton, and study the modeling of such a food chain and analyze their behaviors by numerical s… Show more
