The cycle can be completed by identifying all the four stages how CO2 is being taken by plant.
What is the process of absorption of CO2 by plants ?
Plants use energy from light to convert water and carbon dioxide into sugar and oxygen in a process called photosynthesis. Chlorophyll, the green pigment in leaves, absorbs sunlight and uses the energy to convert six molecules of carbon dioxide and six molecules of water into one molecule of sugar and six molecules of oxygen. Plants use the sugar to grow and release the oxygen back into the atmosphere. They also help regulate the amount of carbon dioxide, which is one of the most important greenhouse gases, in the atmosphere.
The cycle model diagram is attached for the reference of the steps through all the four spheres.
