An electric air pump oxygenates the water in an aquarium, this allows the fish in the fish tank to breath. if there was no air pump the water would lose its oxygen and the fish would drown.

Probably with an aquarium pump.
The main usefull purpose of an "Air Pump" is to drive/operate a filter and cycled filters are an absolute neccessity for all fish in any aquaria. Air bubbles do very little to improve things in an aquarium so if you have a power filter the air pump would be superfluous.
No, a filter in an aquarium does not provide oxygen. It helps to clean the water by removing waste and debris, but oxygen is typically added to the water through an air pump or other means to ensure the fish have enough oxygen to breathe.
An air pump is a pump which transmits air into or out of something.
Mount Air was created in 1801.
An air pump attached to an airline, which is then attached to either a bubble wand, air stone, or a bubble disc will help to oxygenate water in an aquarium.This should be used in conjunction to a filter, either an HOB (Hang On Back) or a canister filter for example; one is certainly not the same as the other.
Aquarium air pumps are almost exclusively sold at pet stores. Just about any local pet store should carry some models, and the larger chain stores like Pet Co and Pet Smart will definitely have a wide selection. Pet Co and Pet Smart also feature online stores to order from.
Bettas do not necessarily need an air pump, as they have a labyrinth organ that allows them to breathe air at the water's surface. However, an air pump can help increase oxygen levels in the water and provide additional surface agitation, which can benefit the overall health of the betta and other aquarium inhabitants.
