i need an explanation of OXYGEN CYCLE with a diagram .


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 COinto 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 COinto the atmosphere as a by product along with other gases like Netc.

Step5)COis 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.
