The correct answer is:

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

While carbon dioxide is used by organisms (mainly through the process of photosynthesis), a significant amount of it is also stored in carbon sinks, which include the oceans, forests, and soils. These sinks temporarily hold carbon and play a critical role in the global carbon cycle.
