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
