D. Nitrosomonas
E. Nitrobacter
Final answer: Nitrate is produced in the oxidation stage of the aquaponic nitrogen cycle by Nitrobacter and Nitrosomonas.
Answer:
Nitrate is produced in the oxidation stage of the aquaponic nitrogen cycle by Nitrobacter and Nitrosomonas.
The production of nitrate in the aquaponic nitrogen cycle occurs during the oxidation stage. This process involves the conversion of nitrite to nitrate by specific bacteria, namely Nitrobacter and Nitrosomonas.
Nitrosomonas is responsible for converting ammonia to nitrite, while Nitrobacter further oxidizes the nitrite into nitrate. These bacteria play a crucial role in nitrification, a key process in aquaponics that helps regulate nitrogen levels in the system.
Understanding where nitrate is produced in the aquaponic nitrogen cycle is essential for maintaining water quality and ensuring the overall health of the aquatic and plant life in the system. By promoting the growth and activity of Nitrobacter and Nitrosomonas, aquaponic practitioners can support proper nitrification and nutrient cycling within their systems.
