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.

The CARBON Cycle

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.
What is a carbon atom?

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. -
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

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

20. 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 + 6CO > C6H12O6+ 6O2
6 molecules of water + 6 molecules of carbon dioxide = 1 molecule of sugar molecules of oxygen
How do plants do it? Through photosynthesis!

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

22. Photosynthesis & Food TedEd Video clip

23. 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

24. 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.

31. The Nitrogen Cycle

32. 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

33. “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…

34. 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”

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.
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

37. Simple Picture

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

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.
In Conclusion, Remember…
