What is the ecosystem model?
ecosystem model is the representation of the ecosystem listed in mathematical form. Such models are used in theoretical ecology that help ecologists study existing ecosystems and predict what could happen under certain conditions. The ecosystem is incredibly complex, so the ecosystem model must generally simplify the system by focusing only on specific parts.
ecosystems are a biological environment. They include all living creatures in a particular area and the physical properties of this area that could affect or be used by organisms in it. These can be things like air, water or the amount of sunlight. The model must also take into account the size of the studied environment, as this can affect the organisms in it.
In order to create a feasible mathematical model, the ecologist must simplify the ecosystem he is trying to study. This can be done by focusing on a limited number of species or groups that share certain properties. These trait could be behavioral, biochemick or physical.
As soon as the ecologist isolated interesting organisms, they create a food chain for them. The food chain is a representation of the relationships of predatory prey. For example, if an animal that is an interesting coyote, the food chain can show that the coyote eats rabbits who eat vegetation at the ground level. Empire, rabbits and vegetation will become elements in the ecosystem model.
Elements in the ecosystem model are then connected using mathematical functions that describe their relationships. Again, the complexity of the ecosystem is a problem for the ecologist. It is difficult to observe what the real influence on the consumption of a single rabbit will have a coyotes on the population, so ecologists use statistics, observation and other methods to reach an educated estimate. Mathematical functions may be as a real event in the ecosystem demonstrate or refute the accuracy of the ecosystem model.
classic ekosys modelThese ecology students are the Predator-Kořista model created in the middle of the age of 20. Two scientists were created separately in the area of one year: American mathematician, chemist and statistics Alfred J Lat and Italian mathematician and physicist Vito Volterra. Their model uses a few differential equations to represent predators and prey. Although it is originally used to describe fluctuations in shark and fish populations in the Adriatic Sea, the model acts as a general description of the Predator-Kořist relationship.
