Water Cycle

1. Sun2. Clouds/

Condensation3. Evaporation4. Precipitation5. Ocean6. Where can we draw

transpiration?1. Transpiration is the

evaporation of water from plants

Carbon Cycle

Two Major Processes: Cellular Respiration:

O2 + Glucose CO2 + H2O

Photosynthesis: CO2 + H2O Glucose +

O2

Nitrogen Cycle

Nitrogen is a major component in protein and DNA

• Found in water as -ammonia (excreted by aquatic animals)-nitrites (formed by bacteria)-nitrates (formed by bacteria)

Phosphorus Cycle

Phosphorous is a major component in DNA and ATP

Initially comes from weathered rock
