【評論內容】There are primarily three types of vertical farming—hydroponics, aquaponics and aeroponics. Hydroponics is the growing process where crops are grown with their roots submerged in a nutrient-rich water solution. This method is also getting more and more common in urban areas today. The second method, aquaponics, is a sustainable food production system where crops are grown in water that contains waste from fish, and they in turn clean the water for the fish. Finally, aeroponics refers to the process of growing crops with their roots suspended in the air. Farmers practicing aeroponics believe that crops will become healthier and grow faster when their roots have greater access to oxygen.Which of the following is a major difference between hydroponics and aquaponics?
