3-5 sentences, explain why or why not. (4 points)

Answer 1

Yes, the biosphere is necessary for the carbon cycle. The carbon cycle involves the exchange of carbon between various components of the Earth, including the atmosphere, oceans, and land. The biosphere plays a crucial role as it includes all living organisms that interact with carbon in different ways. Photosynthesis by plants and other organisms helps remove carbon dioxide from the atmosphere, while respiration and decomposition release carbon dioxide back into the atmosphere. Without the biosphere, these processes would not occur, disrupting the carbon cycle and leading to imbalances in the carbon dioxide levels in the atmosphere.
