What is the composition of air how do earthworms breath |
|
Answer» in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. AIR also has small amounts of lots of other gases, too, such as CARBON dioxide, neon, and hydrogen.Worms breathe air in and carbon dioxide out, just LIKE us, but they don't have lungs. They can't breathe through their mouth, and certainly can't breathe through their nose because they don't even have one! They breathe through their SKIN. |
