1. Abiotic Cycles

2. Standard and EQ
Standard
Essential Question
SZ4. Students will assess how animals interact with their environment including key adaptations found within animal taxa. 
How are elements recycled and reused in nature?

3. Water Cycle

4. Evaporation
When water returns to the atmosphere from lakes, rivers, etc. in the form of vapor. 

5. Transpiration
When the water returning to the atmosphere is in the form of vapor from plants.

6. Condensation
When water vapor becomes liquid in the form of clouds.

7. Precipitation
When liquid water from clouds falls back to earth as rain, hail, sleet and snow

8. Run Off
Water from precipitation flows back into lakes and rivers.

9. Carbon Cycle
Carbon cycles from the atmosphere to organisms and back into the atmosphere

10. Photosynthesis
Plants use carbon in carbon dioxide from the atmosphere to make glucose.

11. Consumption
Consumers get carbon from glucose by eating plants for energy.

12. Cell Respiration
Carbon is returned to the atmosphere as carbon dioxide when consumers breath out.

13. Fossil Fuels
Carbon from dead organisms decays into petroleum in the ground (fossil fuels)

14. Burning Fossil Fuels
We burn fossil fuels (gas, oil, coal) and release the trapped carbon as carbon dioxide into the atmosphere

15. Nitrogen Cycle We use nitrogen to make proteins
Almost 80% of air is made of nitrogen, but it is in a form plants and animals cannot use (N2).

16. Nitrogen Fixation
Lightening and some Bacteria that live in soil and roots can turn nitrogen from the air into a form plants can absorb.

17. Consumption
Consumers get nitrogen by eating

18. Ammonification
Ammonification is when consumers release waste, returning nitrogen to the soil in the form of ammonia (NH3)

19. Denitrification
Some bacteria break down ammonia and return nitrogen to the atmosphere as N2.
