319136051Precipitationthe falling to earth of any form of water (rain or snow or hail or sleet or mist)
319136052EvaporationLiquid to Gas
319136053Transpirationthe process by which plants release water vapor into the air through openings in their leaves known as stomata
319136054Condensationwhen water cools and changes from a gas to a liquid
319136055Runoffrainfall not absorbed by the soil that runs into streams and rivers
319136056InfiltrationThe seepage of water into soil or rock
319136057Ground waterWater that filters into the ground from the surface; the source of water for springs or wells
319136058Cellular respirationprocess that releases energy by breaking down glucose and other food molecules in the presence of oxygen and carbon dioxide, water and energy is released
319136059Decompositionthe breakdown of dead organisms by bacteria or fungi
319136060Fossil fuelscoal, oil, natural gas, and other fuels that are ancient remains of plants and animals
319136061Climate change..., The change in global climate patterns apparent from the mid to late 20th century onwards, attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
319136062Photosynthesis..., process by which plants and some other organisms use light energy (Sun) to convert water and carbon dioxide into oxygen and glucose
319136063Nitrogen fixationprocess by which certain bacteria convert nitrogen gas to ammonia
319136064Ammonia..., A pungent gas compounded of nitrogen and hydrogen (NH₃) Nitrogen gas (N2) is converted into Ammonia through ammonification
319136067Nitrificationprocess by which bacteria in the soil take up ammonia and convert it into nitrites (NO2) and nitrates (NO3)
319136068ammonificationdecomposers break down the corpses and wastes of organisms releasing the nitrogen as ammonia
319136069Carbon dioxide gas formulaCO2
319136070Water formulaH2O
319136071Ammonia formulaNH3-- is nitrogen plus three hydrogens this compound is found in animal and human waste
319136072Nitrogen formulaN2-- nitorgen gas makes up about 80% of our atmosphere
319136073Oxygen gas formulaO2
319136074NitrateNitrate NO3 is nitorgen plus three oxygens This compound can be absorbed by plants
319136075Water cyclethe continuous process by which water moves from Earth's surface to the atmosphere and back
319136076Carbon Oxygen cycleThe movement of carbon and oxygen through the environment. Involves respiration, photosynthesis, decomposition, burning of oxygen, and plants and animals.
319136077Nitrogen cyclethe transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere, the cycle in which nitrogen gas is changed into forms of nitrogen that plants can use
319136078Why is bacteria important to the nitrogen cycle ?Other than lightning, only certain bacteria can take nitrogen and convert it into a usable form
319140661Hydrologic cycleanother name for the water cycle
323374887Nitrite formulaNO2 Nitrite Nitrogen plus two oxygens This compound is used by bacteria to change ammonia (NH3) into nitrate (NO3)
323379950why do living things need carbon?carbon is found in all living things & is necessary to life. It is the essential ingredient in carbohydrate molecules because carbon is needed to store energy.
323379951why do living things need oxygen?Oxygen is needed to all living things because it is required for the process of cellular respiration because it is needed to release energy.
323379952How is carbon stored inside living organisms?Organic Compounds: Carbs, Lipids (fats), Proteins, Nucleic Acids
323379953In what form does carbon leave an organismthrough cellular respiration it leaves as CO2
323379954In what form is carbon extracted from the ground?Fossil fuels (stored carbon)
323379955In what form is carbon found when it is being burned by a factory or a car?Through combustion it is found as CO2
323379956Carbon Dioxide-Oxygen Cycle (LIST)Plants take in CO2 during photosynthesis They use the CO2 to make food(glucose) They release O2 (oxygen) to the air Animals/humans take O2 in from the air They release CO2 during cellular respiration Decomposers break down dead plants and animals which releases CO2 into atmosphere CYCLE STARTS OVER AGAIN!
323379957Four major elements that make up over 99% of your bodyHONC: Hydrogen Oxygen Nitrogen Carbon
323379958Nitrogen Cycle (LIST)1.Nitrogen(N2) gas in the atmosphere (not in usable form) 2. bacteria in soil "fixes" nitrogen to be in a usable form: N2 to NH3 (ammonia) to Nitrite (NO2) to Nitrate (NO3) 3. Plants absorb Nitrates (NO3) to make proteins 4. animals consume plants 5. animals produce waste -- NH3 (ammonia) 6. ammonification--decomposers break down the corpses and wastes of organisms releasing the nitrogen as ammonia 7.denitrification--conversion of nitrates in the soil by bacteria into nitrogen gas and is released into atmosphere 8. Cycle STARTS OVER
323379959WATER CYCLE ( LIST )1. water gets into atmosphere through evaporation (sun) and transpiration (plants) 2. water condeses into gas form and stored in clouds 3. water returns to liquid through precipitation (rain, snow, hail ) 4. water returns to earth via precipitation in the form of runoff, infiltration, storage (ocean, lakes, underground, ice caps, glaciers) START CYCLE OVER
323480807why do living organisms need nitrogen ?nitrogen is used by the body to make proteins and nucleic acids--necessary for life
323499144denitrificationconversion of nitrates in the soil by bacteria into nitrogen gas
323507087photosynthesis formula6CO2 (carbon dioxide) + 6H2O (water) + sunlight (light energy) => C6H12O6 (sugar) + 6O2 (oxygen) importance: glucose (sugar) drives metabolism and growth in most organisms
323507088cellular respiration formulaC6H12O6 + 6O2 → 6CO2 (carbon dioxide) + 6H2O + energy
