8. Matter, made of elements move through the ecosystem. Key Point #1: Matter is anything that has mass and takes up space Remember: Matter is not created nor destroyed. It is RECYCLED!

9. WATER CYCLE

10. TRANSPIRATION

11. Transpiration  Key Point #2: Transpiration is water passing from a plant to the atmosphere.  Evaporation from a plant!

12. TRANSPIRATION EVAPORATION

13. Evaporation  Key Point #3: Evaporation is water turning from a liquid to a GAS!  From a body of water

14. There is water present in both plants and bodies of water (rivers, lakes, oceans).  a. Water leaves a plant and enters the atmosphere through the process of:  TRANSPIRATION  b. Water leaves a body of water and enters the atmosphere through the process of:  EVAPORATION Do we have it?!

15. TRANSPIRATION EVAPORATION CONDENSATION

16. Condensation  Key Point #4: Condensation is water vapor into liquid  Clouds!

17. TRANSPIRATION EVAPORATION CONDENSATION PRECIPITATION

18. Precipitation  Key Point #5: Precipitation is water that falls from the clouds  Snow, hail, freezing rain, and rain

19. TRANSPIRATION EVAPORATION CONDENSATION PRECIPITATION RUN-OFF COLLECTION GROUNDWATER

20.  Key Point #6: Water runs off and will collect in lakes, ponds, and oceans.  Ground water is water held under the soil

23. NITROGEN CYCLE

24. Nitrogen Cycle There is A LOT of ________ in the air, but plants and animals CAN’T use it! NITROGEN

25. Nitrogen Cycle  Key Point #7:  Fix: bacteria changes nitrogen into ammonia  Nitrogen Fixation

26.  Key Point #8: Plants and animals release nitrogen when they die.  RECYCLING!

27. Plants and animals die and return nitrogen back to the soil. This the nitrogen that needs to be “fixed”.

28.  What is the impact of removing ALL of the bacteria from the world? Turn and Talk

29.  Answer the following questions on a half sheet of paper for page 29! 1. After millions of years, what do decaying plants and animals turn into? 2. What process is very similar to evaporation? 3. When water from lakes goes into the air, what process is this called? 4. What form does nitrogen need to be in order for plants to use it? 5. When it snows, what part of the water cycle is this? 6. What part of the water cycle is it when water leaves plants and goes into the air as water vapor? 7. What organisms collect nitrogen in the air and change it into a form plants can use? 8. How do animals get their nitrogen? 9. When water vapor changes into clouds, what process is this called? 10. Name two different types of precipitation. Work Time
