Final answer:
The atmosphere and biosphere interact through the biological carbon cycle, where organisms like plants absorb atmospheric CO₂ for photosynthesis, contributing to the interconnectedness of all life and the global carbon cycle.
Step-by-step explanation:
The Earth's atmosphere interacts with the biosphere through various processes, including the biological carbon cycle. Living organisms, including plants (autotrophs), absorb carbon dioxide (CO₂) from the atmosphere to produce glucose (C₆H₁₂O₆) through photosynthesis, a process that also releases oxygen back into the atmosphere. This exchange of gases is essential for life and highlights the intricate connections between living organisms and their environment. Moreover, the carbon exchange connects all organisms, as the carbon in our DNA may have once been part of other forms of life, such as plants or even dinosaurs. Carbon is cycled between different reservoirs including the atmosphere, oceans, ocean sediment, soil, rocks, and Earth's interior, which all play roles in the larger biogeochemical carbon cycle.
