Of the 92 naturally occurring elements, living things are composed of only about 25, and SIX of those make up practically all of the weight of most living things.
Living things are mostly carbon, hydrogen, oxygen, and nitrogen.
The Earth is mostly iron, silicon, and oxygen.
Both incorporate lots of trace elements.
carbon and water

The predominant elements in living organisms are the four CHON elements; Carbon, Hydrogen, Oxygen and Nitrogen.
Your answer is your question. Living organisms contain only elements that are commonly found in living organisms. Now if you knew how to pose a question without an entire universe of variables you might get a better answer. Oh and while you are getting specific enough that someone else could possibly understand your question try not to use two mutually exclusive terms in the same question. Only and commonly in the same question makes it even harder to understand what you are talking about. Why not stick to perfectly normal nonsensical questions? Here are some examples... What if dogs were cats? How many aliens are inside one persons imagination? Why is my coffee colder than it was when I bought it?
The complexity of living systems is commonly found in their structure and function of the organisms. This complexity involves species, organisms, biosphere and biological evolution and is still being researched.
Proteins are found in all living elements.
C,H,O,N,P,S and some mineral elements like Ca,Na,K,Fe, and salty anion of Cl, and a lot of trace elements.Elements that are commonly found in living organisms include carbon (C), nitrogen (N), hydrogen (H), oxygen (O), phosphorus (P), sulfur (S), calcium (Ca), and iron (Fe).
No, all the chemical elements that are found in living things are also found in other places.
in living organisms
hydrogen
Carbon
Let's see. Oxygen, carbon, nitrogen, sulphur, potassium, chlorine, iodine, strontium, hydrogen, (any more anyone?) incidentally, ALL elements are found in the Periodic Table!!
