Answer:
The purpose of the carbon cycle is to utilize the carbon by the organisms such as plant which uses carbon in the form of carbondioxide for making food. This carbon is stored in the form of glucose. When this food is eaten by the animals, it is broken down into simpler substances and carbondioxode is released in the atmosphere again.
Some carbon is present in soil which is used by microorganisms such as bacteria. So carbon cycle is very important for the survival of life on earth.
