Question

What are the four essential elements for life $ ? $

Answer 1

Hint :Here we have to write the four essential elements for life. First, we understand what is an element. How elements become essential for life. Then write the four important elements which are important to life.

Complete Step By Step Answer:
An element is a substance whose all atoms have the same number of protons.
The four essential elements of life are Oxygen $ \left( O \right) $ , hydrogen $ \left( H \right) $ , nitrogen $ \left( N \right) $ and phosphorus $ \left( N \right) $ . These four elements are found in abundance in both the human body and in animals. There are other elements that compose the human body, but the four we've highlighted participate in all life processes. Oxygen is the pivot (central point, pin), which produces water and air and it is absolutely necessary to life. Two hydrogen atoms bonded with oxygen atoms to produce water, if there was no water there would be no life on earth. Nitrogen with oxygen constitutes basic elements of air that compose the Earth's atmosphere. Phosphorus is the last element of the human energy chain. It is the fire and light. In other words, the human energy chain consists of four basic elements, or three compounds: Water, air and fire (light).

Note :
Note that if we consider the chain of human genes, accounts must also be taken of the element carbon. Hence, the four elements of life become the five elements of life: Oxygen, hydrogen, nitrogen, phosphorus and carbon participate in all life processes.
