Answer:
Swim bladder
Explanation:
Swim bladder is an organ in bony fishes such as catfish that controls their buoyancy. It is also known as air bladder. The swim bladder contains gas, mainly oxygen and functions as a hydrostatic organ.
As the fish moves in deeper water, the gas in the swim bladder is contracted which decreases the volume of swim bladder.
The gasoline engine where the air and fuel mixture is burned is called the combustion chamber. A piston is used to increase and decrease the volume which prepares the fuel to be mixed with air. A spark plug is ignited then to create the combustion thereafter.
