1. Words to know Lithosphere- land Hydrosphere- water Atmosphere- air
Biogeochemical Cycles

2. Biogeochemical Cycles
Water Cycle
Carbon Dioxide / Oxygen Cycle
Nitrogen Cycle

3. Water Cycle Evaporation – water gains energy
Condensation – water loses energy
Precipitation – water falling from the sky
Transpiration – water vapor emitted from plants
Runoff – water traveling on the Earth’s surface
Ground water – fresh water trapped underground

4. Oxygen/Carbon Dioxide Cycle
The movement of oxygen and carbon dioxide throughout the lithosphere, atmosphere, hydrosphere, plants, and animals.

5. Processes that move O2 and CO2 through our environment
Photosynthesis
Cellular Respiration

6. Photosynthesis
The process by which plants use sunlight to convert CO2 and H2O into sugar and O2.
Photosynthesis takes place in the chloroplast.
Converts the sun’s energy into chemical energy.

8. Equation for Photosynthesis

9. So we have sugar, now what?

10. Cellular Respiration
is the process by which the chemical energy of sugar (food) molecules is released.
Oxygen is used, to break the bonds of the sugar and energy is released, along with CO2 and H2O.

11. Cellular Respiration Equation
C6H12O6 + 6O2 6H2O + 6CO2 + E
