- As a result of photosynthesis, carbon in the structure of carbon dioxide gas passes into the structure of food.The food formed passes into the structure of other living things through the food chain.With the death of living things, decomposers convert some of the carbon in the structure of living things to carbon dioxide, allowing it to mix into the air again.The remaining part decomposes and mixes with the soil and underground.After millions of years, some of them can be compressed under pressure and turn into fossil fuels such as oil and coal. With the burning of fossil fuels, a large amount of carbon dioxide will be released and the cycle will be re-entered.
