Why are the oceans considered a large carbon sink?
A.) Carbon gets transferred among all the organisms of every food chain.
B.) Water absorbs carbon directly from the atmosphere by diffusion.
C.) Decomposition rates in the water are far greater than on land.
D.) Phytoplankton takes in carbon through cellular respiration.
B.) Water absorbs carbon directly from the atmosphere by diffusion.
The oceans are considered a large carbon sink because they have the ability to absorb and store a significant amount of carbon dioxide from the atmosphere. This is primarily due to the process of diffusion, where carbon dioxide naturally moves from an area of higher concentration (in the atmosphere) to an area of lower concentration (in the ocean). This process helps to regulate the amount of carbon dioxide in the atmosphere and mitigate the effects of climate change.
