interrelationships among organisms and between organisms, as well as how organisms interact with their environment. This means that ecologists might study the behavior of a single species to see how it interacts with other organisms and the environment. Or, an ecologist might study many different species that either depend on each other (a foodweb, for example), or compete with each other for food and space.
