Question
How is the growth of land plants proof that there is carbon in the atmosphere? How does carbon exist in the atmosphere, biosphere, and geosphere all at the same time? (Site 1 )

The growth of land plants requires carbon as a major component of their organic matter. As they perform photosynthesis, they absorb carbon dioxide (CO2) from the atmosphere and convert it into organic compounds such as sugars and starches, which make up their leaves, stems, and roots. Thus, the fact that land plants can grow and reproduce indicates that there is an adequate supply of carbon in the atmosphere for them to utilize.
Carbon exists in the atmosphere as CO2 gas, which is a natural component of the air we breathe. It is also found in living organisms within the biosphere, where it is constantly cycling through various forms like carbon dioxide, carbohydrates, or fats. Finally, carbon also exists in the geosphere, where it is stored in the form of fossil fuels, soils, rocks, and minerals. The carbon cycle is a continuous process that involves the movement of carbon between these three major reservoirs, driven by natural processes such as photosynthesis, respiration, decomposition, erosion, and volcanic activity. Overall, carbon plays a fundamental role in shaping our planet's climate, ecosystems, and geological history.
