GEOG 125 Lecture Notes - Lecture 2: Dynamic Equilibrium, Homeostasis, Denitrification
Document Summary
A system is a set of components that are functionally connected. An ordered and interrelated set of actions or materials that functions as a unit or whole A network of relationships among parts, elements or components that interact with and influence one another. Function and interact in a regular and theoretically understandable manner. Understanding systems also depends on whether they are viewed from inside or outside. Important in recognizing systems and understanding their behaviour. Space and time scales: natural processes differ dramatically. Effect of spatial scale on defining a system. Effect of temporal scale on understanding operation of a system. Of both water and hydrogen for life processes. Organic matter transformed from air, water, and rock. Light reaction = splits water by using solar energy. Calvin cycle = links carbon atoms from carbon dioxide into sugar (glucose) 6co2 + 6h2o + solar energy ---> c6h12o6 + 6o2.
