Question

Quizplus · Accepted Answer

Pollen is best preserved in acidic and poorly aerated environments such as peat bogs and lake beds, which are wetlands with low levels of oxygen. The acidity of the sediment helps to slow down the process of decay, while the lack of oxygen prevents the growth of organisms that would otherwise decompose the organic matter. These conditions allow for the exceptional preservation of pollen grains over thousands of years.
