Document Summary
Chapter 3 environmental systems and ecosystem ecology (textbook notes) (62) earth"s environmental systems - includes cycles shape the landscape around us and guide the flow of elements and compounds that support and regulate life. System network of relationships among parts, elements, or components that interact with and influence one another through the exchange of energy, matter or information, process these inputs and make outputs. Open systems systems that receive inputs of energy and matter. Closed systems systems that receive inputs and produce outputs of and produce outputs energy, but not matter. Negative feedback loop output that results from a system moving in one direction acts as input that moves the system in the other direction. Input/output neutralize each other => stabilizing system: they regulate our temp. Positive feedback loop have the opposite effect. Rather than stabilizing a system, they drive it further toward one extreme or another.
