1.Nitrogen Fixation-Nitrogen gas from the air is converted into ammonium, NH3 (which becomes ammonia, NH4+, when mixed with water) by using the enzyme Nitrogenase.
Consumption- The Carrasius auratus are the fish in the tank consuming fish foods.
Decomposition- Ocimum basilicum, or basil, will break down the wastes of the Carrasius auratus into amino acids and other nitrogen containing molecules. Ammonification- waste from the fish is broken down by decomposing bacteria to create ammonia.
2.Nitrification- Next, nitrifying bacteria convert NH4+ into NO3- and NO2- ,which are even easier for the plants to use.
3.Denitrification- Finally, denitrifiying bacteria take the NO3- and NO2- and convert them back into N2 gas in the atmosphere to start the cycle anew.

Autotrophs: Ocimum bacilicum
Nitrosomonas europea
Heterotrophs: Carassius auratus
Processes:
1. Gross Productivity and Net Productivity: The gross productivity is determined by how quickly the autotrophs synthesize glucose. THe net productivity is determined by how much biomass is created after the glucose that is used for energy is used up. The gross and net productivity of our system is affected by the amount of direct light the plants get each day which is about 15 hours of light. The water temperature also greatly affects the productivity of the plants. The higher the temperature of the water, the less disolved oxygen there is in the water which is an indication of a drop in gross and net productivity.
2. Photosynthesis: Photosynthesis occurs in the Ocimum bacilicum plants. Photosynthesis is what converts the nitrate from the water to nitrite and utilizes the nitrate.
3. Respiration: Respiration also occurs in the plants to convert the glucose to energy to create more biomass.
