How do scientists use modeling to study ecological changes?
For example a scientist might study temperature change in an ecosystem through time. The scientist would make a model relating time to temperature change. He would probably collect data from the ecosystem periodically and graph the data to see if there is a pattern. If there is a pattern then that pattern can be used as a model to predict the temperature in an ecosystem at a certain time. This is an example of how modeling can be used to study ecological change.
