Bacteria play a crucial role in an aquaponics system by converting fish waste into nutrients that plants can absorb. In an aquaponics system, fish produce ammonia as a waste product, which is toxic to them in high concentrations. Beneficial bacteria in the system then convert this ammonia into nitrites and nitrates through a process called nitrification. These nitrates are then taken up by the plants as a source of nutrients, effectively filtering the water for the fish and creating a balanced ecosystem. This symbiotic relationship between fish, bacteria, and plants is what makes aquaponics such an efficient and sustainable method of growing food.
