What is Oxygen Cycle / Oxygen Cycle

image of Oxygen Cycle

Hey, guys As you know Oxygen (O2) is very important thing to live. But we don't know how it generates. Because if ecosystem only contain 21% of Oxygen and all the living things continue​ breathing Oxygen then the Oxygen level ends in one day. But it never happens. Why?
Now there a process comes to work which we call Oxygen Cycle. Which running continually as a cycle.
So let's find out how it works.


Process of Oxygen Cycle

The process of Oxygen Cycle mean the process of making Oxygen so here we discuss few characters who creates oxygen for the balance of ecosystem.

Biosphere (Photosynthesis)

(I think we have only known this factor.)
As we know human and animal are breathing Oxygen and releasing Carbon dioxide. Now when the plants are making their food (Carbohydrates) in the process of Photosynthesis they take Carbon dioxide to make Carbohydrate with water and sunlight and release Oxygen at the end product.
It's​ only produce 0.1% of Oxygen level.
6CO2 + 6H2O--sunlight--&gt C6H12O6 + 6O2
Where: 6CO2= Carbon dioxide
           H2O= water
         Light needed​
          C6H12O6= Glucose.
         O2=Oxygen

Lithosphere (Earth's crust)

It is a very important source to produce oxygen almost 99.5% of Oxygen level. Oxygen mostly occur from the crust of earth , it mean the Oxygen is also available in crust of earth in solid state​ like oxide and silicate. But when any natural hazards broke the earth's crust, its automatically realising oxygen in air from minerals. And also in the other hand minerals also take oxygen like when iron comes to attach with oxygen and water it's generate rust.
But during such chemical and weathering process also realise oxygen to atmosphere.

The Atmosphere (Air)

The atmosphere also contains some amount of Oxygen almost 0.33% of Oxygen level. A process calls photolysis makes oxygen to air. It happens when ultraviolet rays of sun broke the molecule of nitrous oxide and water vapour which realise oxygen to the atmosphere.

Process that use Oxygen

Respiration: Human and other animals use Oxygen to breathing and release Carbon dioxide.
Combustion: when we burn something like wood, it takes oxygen and release Carbon dioxide.
Decomposition: When plants or animals die ,they decompose by oxygen​ and release Carbon dioxide.
Rusting: When iron and other minerals get rust by oxygen and water.

Process that produce Oxygen

Photosynthesis: Plants are produce Oxygen by the process of Photosynthesis.
Plants use carbon dioxide, sunlight and water to create energy.
Sunlight: Some oxygen produce by sunlight when it react with water vapour.

Faq Related Oxygen Cycle 

1. What is Oxygen Cycle?

The process of Oxygen Cycle mean the process of making Oxygen so here we discuss few characters who creates oxygen for the balance of ecosystem.


2. What are the steps in the oxygen cycle?

There are basically two steps one Photosynthesis and other animal breathing.




Yeah its​ done! Now we completed the berif discussion of Oxygen Cycle. I think it may be important to your school's study.

Features

1. The Central Government have power to make rules and regulations for the protection and improvements of environment. And also controlling the environmental pollution.

2. No person or company have power to carry on a business or operation which cross the limits of environment pollution. The person or company need a permit that he will not cross the limits of pollution , to carry on his business.

3. If anyone​ or a company break the rule. So he have to takes the all responsibility of the effects of Environmental​ pollution. And he also punished by government.

4. The central government or a officer hired by it, have power to take analysis or research of pollution of water , air and land which the person or company is suffering.

5. whoever fails to obey the rules of Environment Act 1986 have been punished or taked fine from the central government or a officer hired by it.

Importance

The Environment Protection Act 1986 comes with the new revulsion towards india. These rules gives more importance to the environment. After this great work, peoples are starts caring about the nature. The problem​ of pollution like Deforestation, Water Pollution and the other environment releted problem starts solving. However peoples are the biggest source of environment pollution till now. And some of people are not taking any steps to stop this. However.
if we want to save our planet so we have to save our environment.

Gey guys I have shortlisted some important some important question of NBU B.A Part1 ENVS General which may helpful to your study.

So finally we have discussed the Environment protection Act 1986. As you know it is a important topic of your​ envs subject. And you have also cleared about this topic. I was given the discussion from a link where he provide a biref article of Environment Protection Act. You can read the article from (here)

And if the article helpful to you then please share the article to your friends and family. And if I forget something or find any Problem you can comment me it will very helpful to me. And also subscribe our newsletter to get more news about NBU'S Study.
