An activity input is an exchange entering an activity from another activity or from the environment. These inputs represent the flows of materials, energy, services, and resources required for an activity to function and produce its outputs. Activity inputs can be either intermediate exchanges from other human activities within the product system or elementary exchanges drawn directly from the natural, social, or economic environment.
