What are the six key elements in living organisms?

Short Answer

Expert verified
The six key elements in living organisms are Carbon (C), Hydrogen (H), Nitrogen (N), Oxygen (O), Phosphorus (P), and Sulfur (S).

Step by step solution

01

Identify the First Element

The first key element in living organisms is Carbon (C). It forms the backbone of organic molecules, which are integral to living beings.
02

Name the Second Element

The second key element is Hydrogen (H). This element is part of water (H2O) and most organic molecules.
03

Highlight the Third Element

The third key element present in living organisms is Nitrogen (N). It is found in proteins, nucleic acids and other important molecules.
04

Specify the Fourth Element

Oxygen (O) is the fourth key element in living organisms. It’s a component of water and almost all other molecules in a living cell. It’s also necessary for the process of respiration.
05

Mention the Fifth Element

Phosphorus (P) is the fifth key element. It is found in ATP (adenosine triphosphate), which is a molecule that stores and transfers energy in cells. It’s also a component of nucleic acids.
06

Disclose the Sixth Element

Sulfur (S) is the sixth key element. It is mainly found in proteins.
