1. Water Carbon Nitrogen Phosphorus
Cycles of Matter 3-3
Water
Carbon
Nitrogen
Phosphorus

2. Strand II Standard II Benchmark I
Understand how the survival of the species depends on biodiversity and on complex interactions, including the cycling of matter and the flow of energy

3. Energy Flow
Energy - Something that gives usable power, capacity to do work
In the biosphere, energy moves from one place to another, is used/changes form.
Energy is not recycled

4. Matter
Something that takes up space, all things are composed of matter
In the biosphere/in ecosystems, matter IS recycled
(Different from energy)

5. Water Cycle

6. Water Cycle Precipitation Condensation Evaporation Transpiration
Storage
Runoff
Seepage/percolation
Root uptake

7. Water Cycle Forms of water – solid, liquid, gas
Chemical change of water?

8. Carbon

9. Carbon Cycle Processes
Biological processes
Photosynthesis
Respiration
Decomposition
Geochemical Processes
Erosion
Volcanic activity

10. Carbon Cycle Processes
Biogeochemical processes
Creation of fossil fuels

11. Carbon Cycle Processes
Human activities

12. Carbon Cycle
Carbon cycle includes both physical change and chemical change (burning – combustion is a chemical reaction)

13. Nitrogen

14. Nitrogen Cycle Nitrogen Gas – 78% of atmosphere
All organisms need/have nitrogen
Nitrogen as organism waste product
Nitrogen in many different chemical forms
Both physical and chemical changes

15. Phosphorus

16. Phosphorus Cycle
Needed by all organisms, an important component of DNA
Relatively rare in the biosphere
Both chemical and physical changes
Not in the atmosphere
