Special emphasis in the Core is given to the effects of biological processes on Earth systems. Three major concepts underlying the operation of Earth systems may be summarized as matter cycles, energy flows, and life webs. The web of life is intertwined with Earth's energy flows and matter cycles. Emphasis is placed on the inter-connections among Earth's systems and on understanding how alterations in one part may affect the system as a whole.
