<h2>Answer: decreases</h2>
Every substance, body or material has mass and volume, however the mass of different substances occupy different volumes.
This is where density appears as a physical characteristic property of matter that establishes a relationship between the mass
of a body or substance and the volume
it occupies.
So, according to this equation, the density is inversely ptoportional to the volume:
If the volume increases, the density decreases.
This is what a fish does to have buoyancy, since the density of a body is related to its buoyancy:
A body will float on another fluid if its density is lower.
<h2>This is what the fish does when it expands its air bladder, incrementing its volume, hence decreasing its density.</h2>
