The Chemical Cycles

By: Nikko and Lydia

Page 2: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

The 3 Main Cycles

• Carbon cycle• Nitrogen cycle• Phosphorus cycle• 2 broad divisions• Elements that have a gaseous form• Elements that do not have a gaseous form

Page 3: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

• Makes up organic matter• Terrestrial • Aquatic• Cycle is based on C02 Which is a gas• Plants use photosynthesis To make Oxygen from C02• Oxygen supports Animals

The Carbon Cycle

Page 4: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

Carbon cycle: Terrestrial

• Animals use oxygen and return CO2 • Carbon: used by producers, consumers,

decomposers• Cycle quickly in air and water• Can be stored in biomass (trees, plants)• Carbon in plants under the earth eventually turn

into Fossil fuels 

Page 5: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

Carbon Cycle: Aquatic

• CO2 In aquatic ecosystem can be stored in rocks and sediment

• Longer Time to release: Weathering Geoligic processes• In water Stored as Carbonate or bio carbonate ions• Ions keep water "alive" • Sun warms the Carbonate and ions,then   CO2 is

realeased into atmosphere

The Nitrogen Cycle 

• Invovles nitrogen gas• Nitrogen fixing• Assimilation• Ammonification • Nitrification• Dentrification

Page 8: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

Nitrogen Fixing

• One procces of removing nitrogen form the atmosphere • Very expensive• Uses bacteria to remove the nitrogen gas

Page 9: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

Assimilation

• Takes up: Ammonium ion and ntrate ion• From soil by plants• Animals consume the organic nitrogen in the plants   • As amino acids, nucleic acids

Page 10: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

Ammonification

• Organic nitrogen converting back to ammonium ions• Perfomed bacteria and fungal decomposers

Page 11: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

Nitrification

• The different conversions of nitrogen in soil • Converted into amonium ions• Some plants use it• Mostly used by aerobic bacteria • Bacteria oxidizes the the amonium to nitrite• Then to nitrate

Page 12: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

Dentrification

• Also by soil bacteria • Involves the reduction of nitrogen • Some bacteria can get oxygen they need from

nitrate

Global nitrogen process

The Water cycle

• Has three major processes• The sun's energy evaporates water

from land and water surfaces• As it cools, water vapor condences

and falls to earth as precipitation (rain, snow, hail, or sleet) 

• Plants then absorb the fresh water from the soil

Page 16: The Chemical Cycles By: Nikko and Lydia The 3 Main Cycles Carbon cycle Nitrogen cycle Phosphorus cycle 2 broad divisions Elements that have a gaseous

The Water Cycle (continued)

• A large amount of water exits plants during transpiration, evaporation from the plant's leaves

• Water that doesn't enter plantsor absorbed into soil runs off into rivers and streams
