sulfur is the LEAST abundant in living organisms among the options.
Living organisms are composed of Chemical elements which constitute the build up organelles, cells, tissues, and organs.
The Chemical elements are divided into:
- Essential elements : These essential elements are 11 in number ad also subdivided into the major essential elements which make up about 99% of the human body mass. They include Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus. The remaining five (least essential elements) consists of Sulfur, potassium, sodium, chlorine, and magnesium which make up about 0.85% of the remaining mass.
- Trace elements:.The trace elements comprises of the remaining 0.15% of the human body is comprised of trace elements. Whether they may be essential for life, is still being researched for evidence.
Arranging the essential chemical elements according to abundance in living orgasm we have:
- Oxygen 65.0% of body mass
- Carbon 18%
- Hydrogen 10%
- Nitrogen 3%
- Calcium 1.4 %
- Phosphorus 1.1%
- Potassium 1%
- Sulfur
- Chlorine
- Magnesium
