Sub-components of a system can also have their own set of inputs and outputs that may differ from those of the larger system. Typically, outputs of a subcomponent are either input for another sub-component or become part of the ultimate output of the larger system. Whether or not a system is being considered at the macro or micro level determines what a specific item in a system is considered, and this variable level of detail is referred to as scope. Explicit discussions on scope are more common in a technological discussion as sub-units are considered more discretely in the natural sciences. In ecosystems, for example, sub-units are distinguished in to animals, environment, behaviors, and impacts as opposed to objects, namespaces, methods, and scale. Exceptions to this convention are when nominal data points must be encoded for a scientific model simulation.
