Value of Oxygen and Water in Life/Earth Essay: The connection between oxygen, water, and our life is that the former two cannot exist without the prior, but the vice versa is possible. Our survival primarily depends on oxygen in the air we breathe and water.
We have eventually come up with several ways in which we can use both the resources, oxygen, and water for other than our survival but to make our life easier. The absence of oxygen and water in our body is harmful, but the excess presence of both elements will damage some of our organs. We are giving long and short essays on ‘Value of Oxygen and Water in Our Life/Earth’ for students, along with ten lines about the topic.

Long Essay on Value of Oxygen and Water 500 words in English
Oxygen is a gas that is colorless and odorless and a key element in the composition of several compounds. Almost all organisms need oxygen to survive, but it is only trees and some microbes that can produce oxygen through photosynthesis. Oxygen reaches our body through respiration and absorbed by cells for proper functioning. And oxygen is also required for creating energy.
Fire will extinguish in the absence of oxygen. Earth’s nature provides us oxygen in abundance, and we must keep the resources pollution free so that the air we inhale is not toxic. Water is another crucial element that sustains life and is formed by the amalgamation of two gases, namely hydrogen and oxygen.
The oxygen cycle is the process that involves the production of oxygen by plants and after that an organism (including plants) using oxygen for respiration and releasing carbon dioxide, and this carbon-dioxide again being used for photosynthesis. This cycle of using oxygen maintains the amount of gas in the atmosphere.
Water is also an essential component of our environment that is required to sustain life. Water sources on Earth are rivers, streams, rain, ponds/lakes, underground, seas, and oceans. The water forms a part of the ecosystem called the marine or aquatic ecosystem. Water is the habitat for organisms like fishes, sharks, whales, sea horses, etc. And these organisms are sources of our food and also a contribution to the economic assets. Plants and animals both require water for their growth.
Almost sixty percent of our body is made of water. Water helps in blood circulation, lubrication of joints, keeping our body cool by sweating, releases toxins from our body. Water other than drinking is also used by us to clean ourselves, and bathing is essential for maintaining our body temperature. Water is also used to manufacture several products, generate electricity (hydro-electric power), etc.
Both oxygen and water are essential for survival. Excess of any of these is harmful, like excess of oxygen, cough, muscle turbulence, loss of vision, and can be fatal and excessive consumption of water can harm our kidney. Polluting any of the two resources will result in creating an adverse effect on the environment. We must strive to keep our environment clean so that we can breathe pure air and drink clean water. The conservation of both resources is vital to continue life by maintaining balance in the ecosystem.
Short Essay on Value of Oxygen and Water 150 Words in English
The main elements of this Earth are water and oxygen, which are essential as life depends on them. Oxygen is one of the factors responsible for the formation of water; hence life would not have existed without it. A living organism can survive days without food, but it is nearly impossible to survive without oxygen and water. Through photosynthesis, the plants create oxygen, and in the atmosphere, the amount of oxygen gas is maintained by the constant production and usage of oxygen.
Many mistakes that do not require oxygen and only inhale carbon-dioxide, because plants do require oxygen at night for dark photosynthesis. Even though 70% of our plant consists of water, only a small amount of fresh water is drinkable. It goes without a saying that water is used for several purposes like sanitization, washing, cleaning, cooking, creating, etc. We should be grateful to our nature for providing us with water and oxygen and should always work to keep our environment clean.
10 Lines on Value of Oxygen and Water in English
- Among all the other gases in the atmosphere, the amount of oxygen gas present is 21%.
- Almost eight hundred million people don’t have access to clean water.
- The regulation of the temperature of the Earth depends on water.
- Intake of excess oxygen (when the amount of gas exceeds 50%) can turn lethal, causing oxygen poisoning.
- Drinking excessive water causes water intoxication, which is fatal.
- With the advancement of human civilization, the amount of our life expectancy that has increased in the last fifty years didn’t happen in the previous two million years.
- Before 1961, the atomic weight of oxygen was taken as the standard for calculating the other elements. After that, it was changed to carbon 12.
- One cannot swallow and breathe at the same time, a fun fact that involves water, oxygen, and us.
- China uses almost 65% of extracted freshwater in agriculture.
- Around 85% to 90% of the cells in our body are formed of microbes.
FAQ’s on Value of Oxygen and Water Essay
Question 1.
How much oxygen is present in water?
Answer:
It is known to us that water is made up of one-third of oxygen, i.e., water consists of 2 molecules of hydrogen and one molecule of oxygen. That means there is almost 0.001% of the oxygen present in water.
Question 2.
What happens if oxygen is removed from the ocean or any water?
Answer:
Firstly this will not happen because separating a bond requires a massive amount of energy for fission. But if we for argument’s sake assume this ever to happen, then hydrogen in the water will return to its gaseous state and become light, and the area where there was water will only be left filled with air. All the aquatic organisms will die if oxygen is removed from the water.
Question 3.
What is life?
Answer:
The period in which a physical entity exists and undergoes several biological processes to sustain that existence is filled with several activities, but the main motive of surviving is called life.
Question 4.
How was oxygen formed on Earth?
Answer:
Oxygen was formed on Earth sometime around 2.7 to 2.8 billion years ago by the microorganisms like algae and cyanobacteria through photosynthesis.
