Earth is a unique planet...

1. Earth is a unique planet... Why??

2. Because on Earth there are both..... Abiotic Forms These are non-living things such as soil, rock, water, weather, temperature AND...

3. Biotic Forms These are living things such as plants, animals, single celled organisms Co-existing on Earth

4. 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

5. 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.

6. This interaction between the biotic and the abiotic create different cycles. ·Carbon Cycle ·Nitrogen Cycle ·Water Cycle ·Energy Cycle

7. First Cycle: Carbon Cycle Copy this in your notebook Note the direction of the arrows

9. Draw a line between the questions & the correct answer. A. Exhaling carbon dioxide into the atmosphere & consume Carbohydrates (sugars made by producers in the act of photosynthesis) 1. How is carbon found in the atmosphere? B. Carbon Deposits are fossil fuels – which are once living organisms that have been buried – burying their carbon with them. 2. What role do humans & animals play in cycle? 3. What role do plants play in the cycle? C. Organisms die, get buried & their bodies contain carbon which overtime become coal & oil – fossil fuels 4. How is carbon found in our lithosphere (land)? 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. 5. What contributes to carbon deposits? E. Remove Carbon Dioxide from atmosphere by absorbing it & generate carbohydrates (sugars) in the act of photosynthesis

10. In your notebook, write a paragraph explaining these parts of the Carbon Cycle: Atmosphere - aIR Lithosphere -lAND

11. Second Cycle: Nitrogen Cycle Copy this in your notebook Note the direction of the arrows

12. Click on this website address look for this video introduction. Watch the video: https://www.youtube.com/watch?v=oy8e2HrOh6Q

13. 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. 1. What brings the nitrogen to the ground? 2. How do animals get their needed nitrogen? B. The plentiful amount of nitrogen in the air gets attached to falling rain or lightning strikes and is deposited into the ground. 3. What joins oxygen & nitrogen to make it a solid usable form for plants? C. There is 78% Nitrogen gas in our atmosphere. 4. How is nitrogen put back into the atmosphere? D. Bacteria work to release Nitrogen from Nitrites and Nitrites – some of this released Nitrogen is returned to the atmosphere . 5. What gas dominates the atmosphere? E. Eating certain plants provide animals with their needed nitrogen – which is then used to make proteins,

14. In your notebook, write a paragraph explaining these parts of the Nitrogen Cycle

15. Third Cycle: Energy Cycle Copy this in your notebook

16. Click on this website address look for this video introduction. Watch the video: https://www.youtube.com/watch?v=lnAKICtJIA4 :

17. What do consumers add to the ecosystem? What do producers add to the ecosystem? How role does the soil matter play in the ecosystem? What do decomposer add to the ecosystem?

18. Third cycle: Water

19. What happens to allow clouds to form? How does water return to Earth? How is water removed from the ocean? What is it called when trees sweat? How does water get into the soil?

21. Discuss the Water Cycle

22. Now for a review..... And how do the cycles relate to one another?
