PHYTOGEOGRAPHY * the study of the distribution of plants & their ecosystems, both spatially and temporally Biogeochemical Cycles ** all atoms, elements, molecules, substances, etc get cycled through environment. Some, however, are more important than others. ** those important to organisms (to live, grow, and reproduce), are cycled between the nonliving and living components of the environment, in what are known as the biogeochemical cycles * we will briefly discuss the following: Water, Carbon, Hydrologic (Water) Cycle ** The collection, purification, & distribution of the Earth’s water supply through both the abiotic & biotic components of the environment. * evapotranspiration * condensation * precipitation * run-off * consequences of this flow of water: * causes soil erosion & moves weathered fragments of

rock, adding to erosion in one place & deposition in another * is a major medium for transporting nutrients within the Environment * purification of the water supply as it goes through evaporation & precipitation as it flows through streams & lakes, and as it passes through the ground Carbon Cycle ** the flow of carbon, primarily as carbon dioxide (CO 2 ), through the atmosphere, hydrosphere, lithosphere, * consequences: * key element in controlling the temperatures at the Earth’s surface ; it is a “Greenhouse Gas” * a key element in the formation of organic molecules and compounds, upon which life on earth is based * removed from the air by producers (plants) to make complex carbohydrates * produced during aerobic respiration , primarily by animals, and released back into the air

* stored as an ‘energy’ source in the form of fossil fuels ; released back into the cycle when these are broken down (EX: burned by humans) ** Oxygen and Hydrogen cycle in a similar fashion to Carbon . All three are important elements in carbohydrates. Nitrogen Cycle
