Question

What element is found in all organic molecules $$?$$

Answer 1

Hint: First we have to know what an organic molecule is. When we say a molecule is organic. Then mention the element which is found in almost all organic molecules.

Complete answer:
Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen. Hence carbon elements are found in all organic molecules.
 Carbon is in carbon dioxide, which is a greenhouse gas that works to trap heat close to earth. It helps earth hold the energy it receives from the sun so it doesn't all escape back into space. If it weren't for carbon dioxide, Earth's ocean would be frozen solid.
The three elements that make up over 99 percent of organic molecules are carbon, hydrogen and oxygen. These three combined together to form almost all chemical structures needed for life, including carbohydrates, lipids and proteins.

Note:
Note that the most living things on Earth are made of carbon. Living things need carbon in order to live, grow, and reproduce. Also, carbon is a finite resource that cycles through the Earth in many forms. Also, carbon is so important to life because virtually all molecules in the body contain carbon.
