You can refer the diagram given below to understand about Oxygen cycle.
Oxygen is an important component of everyday life. We cannot survive without oxygen. It comprises about 21% of atmospheric air. It is a component of several biological molecules such as carbohydrates, proteins, nucleic acids, and fats.
Like carbon dioxide, oxygen too is cycled through the process of photosynthesis and respiration. Oxygen is also utilized during combustion or burning.
Steps of oxygen cycle.
Step 1)Animals take in oxygen through the process of respiration. And release CO2 into the atmosphere.
Step 2)Carbon dioxide, released by animals is used in plants in the process of photosynthesis.
Step 3)Plants release oxygen into the atmosphere as a by-product of photosynthesis.
step 4)Fuels need oxygen for combustion so they take oxygen and release CO2 into the atmosphere as a by product along with other gases like N2 etc.
Step5)CO2 is released into the air in the process of decaying of dead animals and plants.
step 6)This CO2 is taken by plants for the process of photosynthesis and O2 is released, and this process continues.
The question that you have asked for carbon cycle can be easily answered by going through the study material of (Chapter No.14, Lesson No. 9) on our website. If you have any doubts, then get back to us!
