    Solution:

    The organ used by fishes to breathe in the air dissolved in water is the gills.
    Oxygen is dissolved in water. Fishes have projections on their skin called gills. Gills are well supplied with blood vessels for the exchange of gases and help fishes to breathe the oxygen dissolved in water. There are thousands of blood vessels present in the gills, which extract the maximum oxygen from the water that flows through the gills.
