Nutrients cycles

The carbon cycle

Processes involved:

• Photosynthesis - takes in co2
• Respiration - produces co2
• Decomposistion - Saprobiotic microorganisms break down dead mater and release co2 through respiration
• Combustion - of fossil fuels and deforestation = releases co2

Nitrogen cycle:

4 main stages

• Ammonification
• Nirogen fixation
• Nitirifcation
• Denitrification

Ammonification:

Saprobiotic microgorganisms break down ammonium containing compounds (such as urea) into ammonium ions in the soil

Nitrogen Fixation:

Nitrogen gas…
