11. Reforestation
the act of planting tree seeds or young trees in an area where there used to be a forest

12. Habitat Restoration
Returning the place where a plant or animal normally lives or grows back into it’s original, natural form

13. Law that protects our nation’s waters:
Clean Water Act

14. Photosynthesis

15. Photosynthesis
The sun is the energy source for most producers in ecosystems
WRITE THIS IN YOUR JOURNALS:
Plants (and other photosynthetic organisms) take water and carbon dioxide from their environment and use energy from the sun to produce sugars

16. Key Idea
Energy is gained through the process of photosynthesis

17. Formula
6CO2 + 6H2O + Light C6H12O6 + 6O2

18. Bill Nye: Photosynthesis
History of photosynthesis & explanation of what it is:
Photosynthesis Parody
Photosynthesis / Respiration Song

19. In your group, explain the process of photosynthesis
Read pg in FOSS Textbook if you need more help

20. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar.
This process uses CO2 and Water and transforms it into Glucose (sugar) which is needed for the plant. Oxygen is released into the air

21. Photosynthesis and Respiration
Photosynthesis and respiration are key processes for the transfer of energy

22. Bill Nye Explanation of Respiration

23. RESPIRATION
Explain in your group the process of respiration

24. Environmental Factors

25. (St 4 CO3 PO5) Enviornmental factors
PO 5. Predict how environmental factors (e.g., floods, droughts, temperature changes) affect survival rates in living
organisms.

26. Environmental factors affect survival rates in living organisms
