Question

How do fish breathe underwater?

Answer 1

Fish breathe underwater through their gills. Gills are specialized organs that extract oxygen from the water as it passes over them. This oxygen is then absorbed into the fish's bloodstream, while carbon dioxide is simultaneously released into the water. This process allows fish to extract oxygen from the water and survive underwater.

Answer 2

Fish breathe underwater through their gills. Gills are feathery organs located on both sides of a fish's head that are equipped to extract oxygen from the water as it passes over them. This process allows fish to extract oxygen from the water and release carbon dioxide, enabling them to breathe while submerged.
