Question

How do fish breathe through their gills?
Why do ducks and crocodiles have webbec​

Answer 1

Answer:

Fish

Instead of breathing air, fish must get their oxygen from the water. ... When the oxygen moves throughout the fish's body, it can then diffuse into areas that have too much carbon dioxide. This carbon dioxide will then be carried out of the bodies through the gills. Just like how we breathe out carbon dioxide

Ducks and Crocodiles

Ducks and Crocodiles use their feet to swim. Their webbed feet are uniquely designed to help them move through the water. A duck's and Crocodiles foot has the ability to become wider. Ducks and Crocodiles use their webbed feet like paddles to provide more surface to push against the water.
