Aerobic
From The Aquarium Wiki
Aerobic is an adjective term meaning "requires oxygen". Many organisms use aerobic processes to produce energy on the cellular level.
Typically the beneficial bacteria responsible for breaking down chemical wastes such as Ammonia and Nitrite into Nitrate are aerobic, and are found in areas such as the filter, tank walls, and surface of the substrate where oxygen dissolved in the water is available.
- The opposite is Anaerobic.
