Final answer:
The cycling of carbon through the biosphere indeed requires the incorporation of inorganic CO₂ into organic molecules, a process that is true and initiated by photosynthesis. Photosynthesis and cellular respiration are both central to this cycle, while human activities like burning fossil fuels and deforestation have impacted the cycle and contributed to climate change.
"The statement is a True"
Step-by-step explanation:
The Carbon Cycle and Organic Molecule Formation
The statement that the cycling of carbon through the biosphere first requires the incorporation of inorganic CO₂ into organic molecules is true. This process is primarily facilitated by photosynthesis, where producers such as plants convert inorganic carbon dioxide (CO₂) from the atmosphere into organic carbon compounds like glucose. This forms the foundation of the carbon cycle, connecting atmospheric carbon with the biosphere. The role of photosynthesis is vital as it initiates the flow of carbon through the food web by producing the organic compounds necessary for life.
During photosynthesis, by using sunlight, water, and carbon dioxide, plants and photosynthetic organisms create glucose and release oxygen. These organic carbon molecules can then be used by the plants themselves for growth and by other organisms that consume the plants. Conversely, cellular respiration in organisms converts organic carbon back into inorganic CO₂, which is released into the atmosphere, thus continuing the cycle.
Human activities such as the burning of fossil fuels and deforestation have dramatically affected the balance of the carbon cycle, leading to higher levels of CO₂ in the atmosphere and contributing to climate change. Understanding and maintaining this carbon balance is essential for the health of our planet's ecosystems and for mitigating environmental issues such as global climate change.
