1 Water, Carbon, and Nitrogen Cycles Write underlined information

2 Fold 3 sheets of paper in order to make 6 flaps and label them according to the example to the left. Cycles The Water Cycle Nitrogen Element/Nitrogen Cycle Carbon Element/ Carbon Cycle Review Questions Greenhouse Effect How to make the flipbook:

3 Attach the cycle pictures into the correct flaps with glue/tape/staples/etc. Write the underlined information into the correct flaps.

4 Title Page: Cycles Unlike 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. Flap # 1

5 Review The Water Cycle 1. Transpiration (from plants) 2. Condensation 3. Evaporation 4. precipitation 5.Accumulation Flap # 2

6 Nitrogen 78% of the atmosphere is N2 gas Nitrogen is present in all living organisms, in proteins, nucleic acids, and other molecules Flap # 3

7 The Nitrogen Cycle Most living organisms can NOT use nitrogenous gas. – Some bacteria (soil bacteria) CAN convert N 2 (gas) into NO 3 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 Flap # 3

8 Bacterial nitrogen fixation N 2 in Atmosphere NH 3 Synthetic fertilizer manufacturer Uptake by producers Reuse by consumers Decomposition excretion Atmospheric nitrogen fixation Uptake by producers Reuse by consumers Decomposition Decomposition excretion NO 3 and NO 2 The Nitrogen Cycle Flap # 3

10 Carbon Carbon is the 4 th most abundant element in the universe and the 2 nd most abundant in the human body. Carbon is present in all known life forms, making it the chemical basis for all life. Flap # 4

11 The Carbon Cycle Carbon 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. Flap # 4

12 The Carbon Cycle (key terms) Respiration- the process where oxygen is taken in and CO2 is given off Combustion- a chemical combination attended by the production of heat, light, and CO2 Photosynthesis- the process in green plants by which sugars are formed from CO2, water, and sunlight Flap #4

13 CO 2 in Atmosphere Photosynthesis feeding Respiration Deposition Carbonate Rocks Deposition Decomposition Fossil fuel Volcanic activity Uplift Erosion Respiration Human activity CO 2 in Ocean Photosynthesis The Carbon Cycle Flap #4

14 The 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! Flap # 5

15 Review Questions: Quiz time! Write the questions into the review questions flap. Write the full answer, not just the letter choice.

16 #1 – The only organisms that can convert nitrogen in the atmosphere into a form useful to living things are nitrogen-fixing Aplants. Bbacteria. Cdetritivores. Danimals. Back of flip book

17 #2 – Carbon is found in the atmosphere in the form of Acarbohydrates. Bcarbon dioxide. Ccalcium carbonate. Dammonia. Back of flip book

18 #3 – Earth's temperature range is maintained by Athe greenhouse effect. Bclimate zones. Cocean currents and winds. Dlatitude differences. Back of flip book

19 #4 – Biologists describe nutrients as moving through cycles because the substances Astart as simple organic forms that plants need. Bprovide “building blocks” and energy that organisms need. Care passed between organisms and the environment and then back to organisms. Dare needed by organisms to carry out life processes. Back of flip book

20 #5 If 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 #6 If nitrogen fixating bacteria were to go extinct, how would that affect the nitrogen cycle? List at least 3 effects that could occur.
