To answer this question, we need to understand the carbon cycle on Earth. The carbon cycle describes the movement of carbon between the various spheres of the Earth, including the atmosphere, biosphere (organisms), hydrosphere (water bodies), and lithosphere (Earth's crust).
Carbon dioxide (CO2) is produced through natural processes like respiration and decomposition, as well as human activities such as burning fossil fuels. Organisms, including plants, algae, and bacteria, use carbon dioxide during photosynthesis to produce organic compounds, like glucose, for their growth and energy needs. This process removes carbon dioxide from the atmosphere.
While some of the carbon dioxide used by organisms is released back into the atmosphere through respiration, a significant portion is stored in carbon sinks. One of the major carbon sinks on Earth is the atmosphere itself. The atmosphere acts as a temporary storage site for carbon dioxide before it gets cycled between various organisms.
Another important carbon sink is the oceans. The oceans absorb and store a large amount of carbon dioxide from the atmosphere due to a process called carbon sequestration. The carbon can remain in the oceans for various periods, ranging from decades to centuries.
Therefore, not all of Earth's carbon dioxide supply is constantly being used by organisms. Some of it is stored in carbon sinks, like the atmosphere and the oceans.
