1Water, Carbon, and Nitrogen Cycles Write underlined information
2How to make the flipbook: CyclesFold 3 sheets of paper in order to make 6 flaps and label them according to the example to the left.The Water CycleNitrogen Element/Nitrogen CycleCarbon Element/ Carbon CycleGreenhouse EffectReview Questions
3How to make the flipbook: Attach the cycle pictures into the correct flaps with glue/tape/staples/etc.Write the underlined information into the correct flaps.
4ALL ELEMENTS MUST BE RECYCLED IN NATURE. Flap # 1Title Page: CyclesUnlike the one-way flow of energy, matter is recycled within ecosystems.This means the kinds and amounts of elements on Earth are relatively constant.Each element in living organisms most likely came from another living organism through the food chain. Therefore, no amounts are being added nor are they leaving the earth.ALL ELEMENTS MUST BE RECYCLED IN NATURE.
5Review The Water Cycle 1. Transpiration (from plants) 2. Condensation Flap # 2Review The Water Cycle1. Transpiration (from plants)2. Condensation3. Evaporation4. precipitation5.Accumulation
6Nitrogen 78% of the atmosphere is N2 gas Flap # 3Nitrogen78% of the atmosphere is N2 gasNitrogen is present in all living organisms, in proteins, nucleic acids, and other molecules
7The Nitrogen Cycle Most living organisms can NOT use nitrogenous gas. Flap # 3The Nitrogen CycleMost living organisms can NOT use nitrogenous gas.Some bacteria (soil bacteria) CAN convert N2 (gas) into NO3 which can be used by plants. This is called nitrogen fixation!Denitrification- conversion of nitrates into nitrogen gas and sends it back into the atmosphere

10Flap # 4CarbonCarbon is the 4th most abundant element in the universe and the 2nd most abundant in the human body.Carbon is present in all known life forms, making it the chemical basis for all life.
11Flap # 4The Carbon CycleCarbon exists in the atmosphere as carbon dioxide gas, and is also present in many other greenhouse gases such as methane.Carbon on Earth moves in a big cycle.Respiration, combustion, and decay of plants and animals ADD carbon dioxide to the air and remove oxygen.Photosynthesis REMOVES carbon dioxide and adds oxygen.The processes should balance out. However, it seems human activity has upset the natural carbon cycle.
12The Carbon Cycle (key terms) Flap #4The Carbon Cycle (key terms)Respiration- the process where oxygen is taken in and CO2 is given offCombustion- a chemical combination attended by the production of heat, light, and CO2Photosynthesis- the process in green plants by which sugars are formed from CO2, water, and sunlight
13The Carbon Cycle Flap #4 CO2 in Atmosphere CO2 in Ocean PhotosynthesisVolcanic activityfeedingRespirationErosionHuman activityRespirationDecompositionCO2 in OceanUpliftCarbon is found in several large reservoirs in the biosphere. In the atmosphere, it is found as carbon dioxide gas; in the oceans as dissolved carbon dioxide; on land in organisms, rocks, and soil; and underground as coal, petroleum, and calcium carbonate rock.

14The Greenhouse Effect. What is it? Flap # 5The Greenhouse Effect. What is it?The greenhouse effect is when carbon dioxide and methane trap heat from the sun.Gases in the atmosphere naturally act like an insulating layer. They absorb most of the heat that would normally be radiated out into space, and re-radiates it in all directions (including back towards the Earth).Increasing temperatures affect ALL organisms!
15Review Questions: Quiz time! Write the questions into the review questions flap.Write the full answer, not just the letter choice.
16Back of flip book#1The only organisms that can convert nitrogen in the atmosphere into a form useful to living things are nitrogen-fixingA plants.B bacteria.C detritivores.D animals.
17#2 Carbon is found in the atmosphere in the form of A carbohydrates. Back of flip book#2Carbon is found in the atmosphere in the form ofA carbohydrates.B carbon dioxide.C calcium carbonate.D ammonia.
18#3 Earth's temperature range is maintained by A the greenhouse effect. Back of flip book#3Earth's temperature range is maintained byA the greenhouse effect.B climate zones.C ocean currents and winds.D latitude differences.
19Back of flip book#4Biologists describe nutrients as moving through cycles because the substancesA start as simple organic forms that plants need.B provide “building blocks” and energy that organisms need.C are passed between organisms and the environment and then back to organisms.D are needed by organisms to carry out life processes.
20#5If volcanic activity were to increase, how would that affect the amount of photosynthesis plants could do? How would this increase in CO2 from the volcanoes affect the greenhouse effect on our planet?
21#6If nitrogen fixating bacteria were to go extinct, how would that affect the nitrogen cycle? List at least 3 effects that could occur.
