Nitrogen Cycle
Found in Air.
Atmospheric Nitrogen (N2)
Nitrogen Fixation
Decompostion
Plants NH3 & NO3
Done by bacteria in the
grow bed.
​
Ammonification
N2 NH3
Basil (Ocimum basilicum), watercress (Nasturtium officinale), and cilantro (Coriandrum sativum) in the growbed take in ammonia for use in proteins and amino acids.
​
NH2 Proteins/animo acids
Bacteria in the grow bed change ammonia to nitrate to nitrite.
​
Nitrification
NH3 NO2 NO3
Bacteria in the grow bed change nitrates back to atmospheric nitrogen.
​
Denitrification
NO3 N2
Basil (Ocimum basilicum), watercress (Nasturtium officinale), and cilantro (Coriandrum sativum) in the growth take in nitrates to use in their own growth.
​
Consumption
NO3 Growth
Carbon Cycle
Occurs when Basil (Ocimum basilicum), watercress (Nasturtium officinale), and cilantro (Coriandrum sativum)dies
​
Decomposition
Plant H2CO3+CO2+C12H22O11+C6H10O5+C6H12O6
Occurs inside of the plants
Glucose+Fructose=Sucrose
C6H12O2+C6H12O2=C12H22O11
Comes from the air.
​
CO2
Occurs in the plants in the grow bed.
​
CO2 C6H12O6
Occurs inside the plants
​
Respiration
C6H12O2 energy+ CO2
Photosynthesis
Nutrients from pool.
Placed in fish tank by humans.
​
Fish food
Occurs in fish
​
Many glucose glycogen
Consumption
Occurs in fish.
​
Respiration
C6H12O2 energy+CO2
Inside the fish tank
​
sunburst platies (Xiphophorus maculatus)
Decomposition
C6H12O2+CO2+glycogen+O2
Energy Flow
Comes from growth lamp.
​
Light Energy
Lamp radiated heat.
​
Energy lost as heat.
O2
In the plants.
​
Photosynthesis
Bacteria decompose dead plants.
​
Plants CO2+ H2o
+CO2H12O6+O2+starch
Fish
Bacteria do it
​
Decomposition
In the Sunburst Platy
​
Respiration
Food
Obtained from humans
In the plants.
​
Respiration
Gross Productivity: Basil (Ocimum basilicum)+ watercress (Nasturtium officinale)+ cilantro (Coriandrum sativum)+sunburst platies (Xiphophorus maculatus)
​
Net Productivity: Gross productivity- energy used in respiration
