Aquaponics System: Understanding the Role of Nitrogen Cycle

What is the major part of an aquaponics system?

a) Oxygen cycle

b) Nitrogen cycle

c) Carbon cycle

d) All of the above

Final answer:

In an aquaponics system, the nitrogen cycle is the major component which facilitates the conversion of fish waste into nutrients for plants.

The major part of an aquaponics system among the listed options is the Nitrogen cycle. In aquaponics, the nitrogen cycle facilitates the conversion of fish waste into nitrites, then nitrates, which plants use as nutrients. This cycle is performed by beneficial bacteria, creating a symbiotic environment where both fish and plants can thrive. While oxygen and carbon cycles are also important in many biological systems, it's the nitrogen cycle that is particularly central to the operation of an aquaponics system.
