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.

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

Precipitation- Condensation Evaporation KEY TERMS DEFINED Any form of water that falls from the clouds; Includes rain, snow, sleet or hail KEY TERMS DEFINED Change of state from GAS to a LIQUID (it condenses) Change of state from LIQUID to a GAS (because of heat)

Transpiration- Runoff- Groundwater- KEY TERMS DEFINED Plants release water vapor into the air (evaporation off of plants) KEY TERMS DEFINED Precipitation that flows over the land and into streams & rivers Water that is beneath Earth’s surface

The Carbon Cycle

Carbon Cycle Diagram Decomposition Photosynthesis Combustion Cellular Respiration Photosynthesis Combustion Decomposition

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? The CARBON Cycle

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. What is a carbon atom?

The CARBON Cycle https://youtu.be/3XIyweZg6Sw

What are the basics of the carbon cycle? Photosynthesis-Plants use carbon dioxide, water, and sunlight to make sugar molecules (glucose) and oxygen. - What are the basics of the carbon cycle? 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

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! What are the basics of the carbon cycle? Simple picture

How do plants do it? Through photosynthesis! The process by which producers use the energy from sunlight to produce sugar, which consumers convert to "fuel“. 6H2O + 6CO2 ----------> C6H12O6+ 6O2 6 molecules of water + 6 molecules of carbon dioxide = 1 molecule of sugar + 6 molecules of oxygen How do plants do it? Through photosynthesis!

The OPPOSITE process… Respiration Respiration- Animals take in oxygen and break down sugar molecules releasing energy, carbon dioxide, and water. C6H12O6+ 6O2 ----------> 6H2O + 6CO2 1 molecule of sugar + 6 molecules of oxygen= 6 molecules of water + 6 molecules of carbon dioxide+ ATP energy! The OPPOSITE process… Respiration

Photosynthesis & Food TedEd Video clip https://youtu.be/eo5XndJaz-Y

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

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

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

Super Sleuth: Find someone who knows… What process takes carbon out of the atmosphere? Photosynthesis takes in what gas? Photosynthesis releases what gas? Photosynthesis Carbon Dioxide Oxygen What 3 processes release carbon into the atmosphere? Cellular respiration takes in what gas? Where do plants get their energy? Respiration, Combustion, Decomposition Oxygen The Sun How do consumers get the carbon they need? Cellular respiration releases what gas? True or False: Animals and plants both perform respiration. Edit boxes for your lesson….students should have a different student in each box..you can print it out and have students initial the box they do for the student. Continue until all boxes are filled. Eat other organisms Carbon Dioxide TRUE

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? The NITROGEN Cycle

“Free” Nitrogen Gas in Air Death & Decay/Decomposition The NITROGEN Cycle “Free” Nitrogen Gas in Air Waste Death & Decay/Decomposition 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…

Take a deep breath. You just breathed in a whole bunch of nitrogen! 78% of earth’s atmosphere consists of Nitrogen. Since nitrogen is so important you’d think this was a good thing, right? Where is nitrogen? Most organisms cannot use nitrogen in the form N2 or “Free Nitrogen”. It must be first combined with other molecules or “Fixed”

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.

Other Ways to “Fix” nitrogen… Lightning can “fix nitrogen” too! This is only a small amount of nitrogen fixation. Other Ways to “Fix” nitrogen… It breaks the bond…nitrogen then combines with oxygen to create NO3 which is washed into the soil by rain. This is the form of nitrogen needed by plants

Simple Picture

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

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. In Conclusion, Remember…
