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.

Where do we get our fresh water?

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.

The CARBON Cycle

What are the basics of the carbon cycle?

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

Simple picture

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?

How do plants do it?Throughphotosynthesis!

PhotosynthesisThe 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

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!

What are the basics of the carbon cycle?

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

How do we get the carbon we need?

Most consumers get the carbon and energy they need by eating plants & animals.

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.

1.What is the % of “free nitrogen” in the air?

2.Define nitrogen fixation

3.Who performs nitrogen fixation? Where do they live?

4.Are there additional ways nitrogen can become “fixed”?

5.How do consumers get the nitrogen they need?

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.
