Earth is a unique planet...
Why??
Because on Earth there are both.....
Abiotic FormsThese are non-living things such as soil, rock, water, weather, temperature
AND...
Biotic FormsThese are living things such as plants, animals, single celled organisms
Co-existing on Earth
Abiotic and Biotic forms work together in establishing an ecosystem
Make a copy of the above chart in your notebook on the next clear page. - Thanks
When you get living things working with non-living things
to create a habitat - exchanges take place between the two.
A common example of this is when an animal digest foods it creates gases. These enter the atmosphere: nitrogen, carbon dioxide, oxygen, methane, and hydrogen sulfide.
This interaction between the biotic and the abiotic create different cycles.

First Cycle: Carbon CycleCopy this in your notebook
Note the direction of the arrows

Watch the video:http://sites.gsu.edu/geog1112/lab-4-2/
1. How is carbon found in the atmosphere?
5. What contributes to
carbon deposits?
3. What role do plants play in the
cycle?
2. What role do humans & animals
play in cycle?
4. How is carbon found in our
lithosphere (land)?
B. Carbon Deposits are fossil fuels – which are once living organisms that have been buried – burying their carbon with them.C. Organisms die, get buried & their bodies contain carbon which overtime become coal & oil – fossil fuels
A. Exhaling carbon dioxide into the atmosphere & consume Carbohydrates (sugars made by producers in the act of photosynthesis)
Draw a line between the questions & the correct answer.
D. Carbon is found as a gas in the air as a chemical Carbon Dioxide which comes from the exhaust of cars, act of animals breathing and industrial smokes.E. Remove Carbon Dioxide from atmosphere by absorbing it & generate carbohydrates (sugars) in the act of photosynthesis
In your notebook, write a paragraph explaining these parts of the Carbon Cycle:
Atmosphere - aIR
Lithosphere -lAND
Second Cycle: Nitrogen CycleCopy this in your notebook
Note the direction of the arrows
Click on this website address look for this video introduction. Watch the video:

5. What gas dominates the atmosphere?
3. What joins oxygen & nitrogen to make it a solid usable form for
plants?
1. What brings the nitrogen to the
ground?
4. How is nitrogen put back into the
atmosphere?
2. How do animals get their needed
nitrogen?
Draw a line between the questions & the correct answer.
A. Special bacteria “fixing” organisms help join oxygen and nitrogen – so plants can easily use the nitrogen to make food for other organisms.B. The plentiful amount of nitrogen in the air gets attached to falling rain or lightning strikes and is deposited into the ground. C. There is 78% Nitrogen gas in our atmosphere.
E. Eating certain plants provide animals with their needed nitrogen – which is then used to make proteins,
D. Bacteria work to release Nitrogen from Nitrites and Nitrites – some of this released Nitrogen is returned to the atmosphere .
In your notebook, write a paragraph explaining these parts of the Nitrogen Cycle
Third Cycle: Energy CycleCopy this in your notebook
Click on this website address look for this video introduction.
Watch the video:https://www.youtube.com/watch?v=lnAKICtJIA4:
What do producers add to the ecosystem?
What do consumers add to the ecosystem?
What do decomposer add to the ecosystem?
How role does the soil matter play in the
ecosystem?
Third cycle: Water
What is it called when trees sweat?
How does water return to Earth?
How is water removed from the ocean?
What happens to allow clouds to form?
How does water get into the soil?
Discuss the Water Cycle
Now for a review.....
And how do the cycles relate to one another?
Function of each in cycle:
Nitrogen Cycle
Carbon Cycle
Water Cycle
EnergyCycle
Lithosphere Bacteria in Soil "fix" the nitrogen in soil.
Decayed matter create fossil fuels - carbons.
Storage space for lakes, rivers, etc.
Fossil fuels store energy.
Atmosphere Lightning makes nitrogen gas into usable solid.
Through respiration - Carbon dioxide gas is created
Transport location for water movement.
Insulator to hold in sun's energy.
Producers (Plants)
Plants bring nitrogen up through roots to form proteins.
Through Photosynthesis - carbon dioxide become sugar.
Absorb water in photosynthesis to make sugars.
Convert sun's energy into sugar.
Consumers (Animals)
Animals get nitrogen from plants to form proteins.
Consuming producers we change sugars into energy and CO2
Consume water to cleanse body systems & releases "used" water.
Use energy converted by plants to power activities.
Decomposers(Scavengers)
Convert dead tissues back into chemical parts - nitrogen goes back to soil
