Answer:

"Assertion Fisheas respire through gills.... Fishes contain internal gills. Gills are thin filamentous structures richly supplied with blood vessels, arranged, so that blood flows in opposite to the flow of water across the gills.

The rate of breathing in aquatic organisms is much faster than in terrestrial organisms because the amount of dissolved oxygen is fairly lower in water than air and also that aquatic organisms like the fishes obtain oxygen from water present in the dissolved state.
