​Aquaponics discussion/review

​Aquaponics combines fish farming and hydroponics. The fish provide nitrogen and organic wastes that fertilize the growing plants, while the plants filter the water for the fish.

​

​How is aquaponics a sustainable solution?

​ -it reuses waste water that is polluted as the fish discharge waste. The waste is providing food/nutrients for the plants, and in turn the plants clean the water the fish live in. This includes the nitrogen cycle as well as cellular respiration and photosynthesis occuring throughout.
