A glance at the given diagram reveals the cycle of carbon in nature.
As depicted, the cycle commences with photosynthesis in trees and vegetation by sunlight, through biological and industrial stages releasing CO2 to restart the cycle again.
To begin with, trees receive the sunlight to cater for photosynthesis process. Subsequently, organic carbon is given off into soil, where it can blend with decay organism. The next stage involves that mixture blending with dead organisms and waste products and emitting into the air based on root respiration priciple.
Along with the emission of root respiration, animal and plant respiration also contibute to the release of CO2. Meanwhile, industrial zones like factories release an amount of CO2 into the air. These emission sources produce CO2 to cater for photosynthesis and start the cycle again.
Overall, the cycle of carbon in nature are based on the principle of respiration of animal and plant as well as photosynthesis.
