The WATER Cycle
Leave space to fill in a
description shortly!
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.
DESCRIBE the following key terms on your poster:PrecipitationCondensationEvaporation Transpiration Runoff Groundwater
The WATER Cycle
Use Ch. 19 section 1
KEY TERMSDEFINED
Precipitation-
Condensation
Evaporation
Any form of water that falls from the clouds; Includes rain, snow, sleet or hail
Change of state from GAS to a LIQUID (it condenses)
Change of state from LIQUID to a GAS (because of heat)
KEY TERMSDEFINED
Transpiration-
Runoff-
Groundwater-
Plants release water vapor into the air (evaporation off of plants)
Precipitation that flows over the land and into streams & rivers
Water that is beneath Earth’s surface
Where do we get our fresh water?

1.The burning of a substance is called __________________. It releases Carbon Dioxide into the air.
2.The process that removes Carbon Dioxide out of the atmosphere in order for plants to make their own food is called ______________.

The Carbon Cycle
Please get out your 19-1 big concept map!

Decomposition
Copy the following key terms on your concept map in the middle box: (leave space to answer them as we go along.)
Photosynthesis Respiration Decomposition Combustion
Include/COPY: How do consumers get the carbon they need?
The CARBON Cycle
What is a carbon atom?
Do NOT copy…just listen!
#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.
As you witnessed yesterday…it CYCLES through land & water!
The ARROWS show where
the CARBON is going…
What are the basics of the carbon cycle?
Define them on your concept map!
Photosynthesis-Plants use carbon dioxide, water, and sunlight to make sugar molecules (glucose) and oxygen.
Respiration- Animals take in oxygen and break down sugar molecules releasing energy, carbon dioxide, and water.
Takes CO2 out of the environment
Releases/Adds CO2 to the environment

The plants give off oxygen, which is what the animals need…
The animals give off carbon dioxide…which is what the plants need!
Just listen…
What are the basics of the carbon cycle?
Define them on your concept map!
Combustion- process of burning a substance, such as wood or fossil fuels
Decomposition- the breakdown of substances into simpler molecules
Releases/Adds CO2 to the environment

Most consumers get the carbon and energy they need… by eating plants & animals.Why is
Carbon Important?
COPY the bold blue parts in the Importance box on the bottom!!
Besides water, the most common molecules in living things are organic molecules, or molecules that contain carbon. (Carbon is found in all organisms)
• Too much carbon may cause Global Warming (heating Earth)

Super Sleuth: Find someone who knows…
What process takes carbon out of the atmosphere?
True or False: Animals and plants both perform respiration.
Photosynthesis takes in what gas?
Where do plants get their energy?
What 3 processes release carbon into the atmosphere?
Cellular respiration releases what gas?
How do consumers get the carbon they need?
Photosynthesis releases what gas?
Cellular respiration takes in what gas?

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 fixationWho 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
The NITROGEN Cycle
“Free” Nitrogen Gas in Air
Nitrogen fixation
WasteDeath &
Decay/Decomposition
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…
Where is nitrogen?
• 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?
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.
• 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
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.
