After studying the historical concentrations of carbon in the oceans for several years, scientists noticed the trend in carbon availability shown in the graph. Based upon this information, they predicted that this pattern would continue.
Based upon the observed data, what is the most valid conclusion that can be made concerning how ocean carbon levels are changing?
The atmosphere has deposited a consistent amount of carbon into the oceans since observations began.
As atmospheric carbon dioxide levels increase, ocean carbon levels decrease along with the pH level.
As atmospheric carbon dioxide levels increase, ocean carbon dioxide levels also increase as the ocean absorbs more carbon.
Additional carbon level readings will show there is no correlation between predicted and observed levels.
The graph is below
