Question

Is all of Earth's carbon dioxide supply constantly being used by organisms? (1 point)
A yes, and it briefly passes through the atmosphere as it cycles between organisms
B no, some is stored in Earth's carbon sinks, such as the oceans
C yes, and it is used up as soon as it is formed
D no, some is stored in Earth's only carbon sink, the atmosphere

Answer 1

The correct answer is **B no, some is stored in Earth's carbon sinks, such as the oceans**.

While living organisms use carbon dioxide for photosynthesis and respiration, a significant portion of carbon dioxide is stored in various carbon sinks, including the oceans, forests, and soil, rather than being constantly cycled through organisms.
