Three main elements that make up a living thing is called?
hydrogen, oxygen, and carbon....
If one thing and three things are in the same room together are they the same if the word thing equals 0?
There are plenty of similarities! Both living and nonliving entities are composed of the same building blocks (or chemical elements), which you can look up in the periodic table. Living things, however, don't make use of all the elements found in the periodic table. And the ratio of elements in living things differs. So, living things might use more carbon, hydrogen, nitrogen and oxygen, in comparison to the other elements.
