module5REVIEW

In this module, we have seen that energy is a fundamental component of environmental systems and that there are different forms of energy. The first and second laws of thermodynamics describe energy behavior. Matter and energy flow within and between systems and are subject to feedbacks that regulate and influence the behavior of systems. Natural systems change, sometimes quickly, sometimes slowly, and change can be natural or caused by human beings.
