The provided diagram shows a simplified model of the global carbon cycle. An increase in atmospheric CO2 increases the rate of the 'Ocean Absorption' flux. However, this process also leads to ocean acidification, which can weaken the biological pump (part of the mechanism sequestering carbon in the deep ocean), thereby reducing the ocean's long-term ability to absorb more CO2. This effect of acidification on the biological pump represents: Figure accompanying this question
