What are the six most common elements in living organisms?
There are several elements that are always found in living organisms. One such element is carbon, which is the molecule that makes up organic compounds. Another is hydrogen, which is in water and is also in most organic molecules in living things. The elements that are found in all living organisms are oxygen, nitrogen, hydrogen, and carbon.
The top 10 most abundant elements in the Universe are hydrogen, helium, oxygen, neon, nitrogen, carbon, silicon, magnesium, iron and sulfur. In the Earth (as a whole) the element iron has the greatest mass. In the relatively thin layer of the Earth's crust (a few hundred to several thousand meters deep) oxygen is the most common (most rocks are aluminum oxides or silicates or silicon oxides) The most common elements found in living organisms are…
