Question

Quizplus · Accepted Answer

During the day, plants photosynthesize, absorbing carbon dioxide and releasing oxygen, which leads to lower atmospheric carbon dioxide concentrations in a forest. At night, photosynthesis stops, but plants and soil organisms continue to respire, releasing carbon dioxide, thus concentrations are typically higher at night.
