2 The Water Cycle

3 CONDENSATION The WATER Cycle: Diagram EVAPORATION PRECIPITATION GROUNDWATER

4 National Science Foundation video clip

5 Why is the water cycle important? Without water, there would be no life on Earth (no water= no life) All organisms are mostly made of water Helps transport nutrients and wastes within an organism Helps regulate temperature. Ex: when you sweat, water evaporates from your skin and cools your body.

6 Where do we get our fresh water? TedEd video clip

7 Describe the following key terms on your poster: The WATER Cycle Precipitation Condensation Evaporation Transpiration Runoff Groundwater Use Ch. 19 section 1

8 Waterour most precious resource.

9 What would happen if you didn t drink water? TedEd video clip

10 Password Round 1 Groundwater runoff respiration transpiration decomposition condensation evaporation photosynthesis combustion precipitation

11 Mind Stretcher copy all 1. During, evaporation the sun s heat causes water to change from liquid to vapor. 2. In, condensation the water vapor cools and returns to a liquid state. 3. The water that falls from the atmosphere to the land and oceans is. precipitation

12 The Carbon Cycle

13 Carbon Cycle Diagram Cellular Respiration Combustion Photosynthesis Decomposition

14 The CARBON Cycle Copy the following key terms on your poster in the middle box: (leave space to answer them as we go along.) photosynthesis respiration decomposition combustion Include: How do consumers get the carbon they need?

15

16 What is a carbon atom? #6 on the periodic table. It s symbol is C. All living organisms are based on the carbon atom. Carbon atoms continually move through living organisms, the oceans, the atmosphere, and the crust of the planet.

17 The CARBON Cycle

18 What are the basics of the carbon cycle? - + Photosynthesis-Plants use carbon dioxide, water, and sunlight to make sugar molecules (glucose) and oxygen. Takes CO2 out of the environment Respiration- Animals take in oxygen and break down sugar molecules releasing energy, carbon dioxide, and water. Releases/Adds CO2 to the environment

19 What are the basics of the carbon cycle? The plants give off oxygen, which is what the animals need The animals give off carbon dioxide which is what the plants need! Simple picture

20 How do plants do it? Through photosynthesis! Photosynthesis The process by which producers use the energy from sunlight to produce sugar, which consumers convert to "fuel. 6H 2 O + 6CO > C 6 H 12 O 6 + 6O 2 6 molecules of water + 6 molecules of carbon dioxide = 1 molecule of sugar + 6 molecules of oxygen

21 The OPPOSITE process Respiration Respiration- Animals take in oxygen and break down sugar molecules releasing energy, carbon dioxide, and water. C 6 H 12 O 6 + 6O > 6H 2 O + 6CO 2 1 molecule of sugar + 6 molecules of oxygen= 6 molecules of water + 6 molecules of carbon dioxide+ ATP energy!

22 Photosynthesis & Food TedEdVideo clip

23 + What are the basics of the carbon cycle? + Combustion- process of burning a substance, such as wood or fossil fuels Releases/Adds CO2 to the environment Decomposition- the breakdown of substances into simpler molecules Releases/Adds CO2 to the environment

24 How do we get the carbon we need? Why is Carbon Important? Most consumers get the carbon and energy they need by eating plants & animals. Besides water, the most common molecules in living things are organic molecules, or molecules that contain carbon (2 nd most common molecule in organisms) Too much carbon may be a cause of Global Warming.

29 Mind Stretcher copy all 1. Carbon dioxide and water are released as waste products of. respiration 2. The breakdown of substances into simpler molecules is called. decomposition

30 What process takes carbon out of the atmosphere? Super Sleuth: Find someone who knows Photosynthesis takes in what gas? Photosynthesis releases what gas? Photosynthesis Carbon Dioxide Oxygen What 3 processes release carbon into the atmosphere? Respiration, Combustion, Decomposition How do consumers get the carbon they need? Eat other organisms Cellular respiration takes in what gas? Oxygen Cellular respiration releases what gas? Carbon Dioxide Where do plants get their energy? The Sun True or False: Animals and plants both perform respiration. TRUE

31 The Nitrogen Cycle

32 The NITROGEN Cycle Describe/Answer the following on your concept map poster in the middle box: What is the % of free nitrogen in the air? Define nitrogen fixation Who performs nitrogen fixation? Where do they live? Are there additional ways nitrogen can become fixed? How do consumers get the nitrogen they need? Why is nitrogen important?

33 The NITROGEN Cycle Free Nitrogen Gas in Air Death & Decay/Decomposition Waste Nitrogen fixation So nitrogen is RELEASED into soil through decomposition when organisms die, through waste, and through bacteria releasing it after being fixed. Nitrogen is RELEASED into the atmosphere by bacteria as well. Plants can then take it in from the soil. Animals then eat the plants

34 Where is nitrogen? Take a deep breath. You just breathed in a whole bunch of nitrogen! 78% of earth s atmosphere consists of Nitrogen. Most organisms cannot use nitrogen in the form N 2 or Free Since nitrogen is so Nitrogen. important you d think this was a good thing, other molecules or Fixed right? It must be first combined with

35 How does nitrogen get fixed? Bacteria who live in nodules on plant roots perform nitrogen fixation. This is an example of mutualism: Bacteria get a home on plant roots Plants get the nitrogen fixed into a form they can use Nitrogen fixation- when bacteria transform nitrogen into a form plants can use Lightning also fixes Nitrogen.

36 Other Ways to Fix nitrogen Lightning can fix nitrogen too! This is only a small amount of nitrogen fixation. It breaks the bond nitrogen then combines with oxygen to create NO 3 which is washed into the soil by rain. This is the form of nitrogen needed by plants

37 Simple Picture

38 Why is Nitrogen Important? All life requires nitrogen. It helps build protein and DNA in our cells

39 In Conclusion, Remember Water, Carbon, and Nitrogen are all necessary to living things. All three are types of matter (non-living) All three are constantly being cycled through producers, consumers, decomposers, and the environment.
