Is all of Earth's carbon dioxide supply constantly being used by organisms? (1 point)

Question

Yes, and it briefly passes through the atmosphere as it cycles between organisms.
Yes, and it is used up as soon as it is formed.
• No, some is stored in Earth's carbon sinks, such as the oceans.
• No, some is stored in Earth's only carbon sink, the atmosphere.

Answer 1

The correct answer is: No, some is stored in Earth's carbon sinks, such as the oceans.

While organisms do utilize carbon dioxide for processes like photosynthesis, not all of the Earth's carbon dioxide supply is being actively used. A significant portion of it is stored in various carbon sinks, including the oceans, soil, and fossil fuels.
