ransportation: The action of transporting someone or something or the process of being transported.
Evaporation: The process of a liquid changing into a gas.
Precipitation: The action or process of precipitating a substance from a solution.
Runoff: Is the flow of water that occurs when excess storm-water, melt-water,or other sources flows over the earth's surface.
Condensation: Is the change of water from its gaseous form (water vapor) into liquid water.
Atmospheric Nitrogen: The conversion of atmospheric nitrogen into a combined form (as ammonia) through chemical and especially biological action (as that of soil rhizobia)
Legumes: A leguminous plant, especially one grown as a crop.
Bacteria: Plural form of bacterium.
Nitrates: A salt or ester of nitric acid, containing the anion NO3
Respiration: A process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
Photosynthesis: The process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. _________ in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Fossil Fuels: A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Hydrocarbons: A compound of hydrogen and carbon, such as any of those which are the chief components of petroleum and natural gas.
Autotrophs: An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
Heterotrophic: A _________ is an organism that cannot fix carbon and uses organic carbon for growth.
