Question

suggest one difference between how fish and humans get their oxygen.

Answer 1

Answer:

fish respires by means of gills

human respires by means of lungs

Answer 2

Answer:

Fish breathe with their gills, and they need a constant supply of oxygen. Gills sit under the operculum. This is called the gill slit. When humans breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
