BIOGEOCHEMICAL CYCLES

Cycles That Occur in Nature. Water cycle  Moves between atmosphere, oceans & land  1 – water evaporates from the ocean  2 – water also evaporates.

Cycling of Matter Energy for life flows in one way – from the source (sun or chemical)

Water Cycle. Transpiration: Excess water is evaporated off the leaves of plants. Evaporation: Water in oceans, lakes, and ponds changes from liquid water.

WATER, CARBON, NITROGEN, & PHOSPHOROUS Chemical Cycles

Water Cycle 1. Sun 2. Clouds/Condensation 3. Evaporation 4. Precipitation 5. Ocean 6. 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
