Penguins are birds, they are not fish, even though they do swim very well. They have lungs and the breathe the same way that any other bird breathes.
through their mouth or nosethey breath through their lungs and mouth
Yes, they do. They have to surface every so often just like other air breathing creatures. They do not have gills like a fish.
its what you breathe and what plants breathe out while they breathe that out they breathe in carbon diOxide and we breathe it out.
Penguins DON'T breathe under water. Penguins breathe with lungs, and need to surface regularly to breathe. While diving, they simply hold their breath.
Humans breathe in oxygen and breathe out carbon dioxide. Trees "breathe" out oxygen.
Humans breathe out carbon dioxide, the whole world runs in a motion, for example plants breathe carbon dioxide, we breathe in oxygen. Even fish breathe oxygen. They take the oxygen out of the water. So we breathe in what plants breathe out and plants breathe in what we breathe out.
