Increased rate of photosynthesis is the most likely explanation as to why atmospheric CO2 levels appear lowest during glacial periods of Earth's history.
<h3>What is photosynthesis ?</h3>
Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities. The process of creating sugars and starches from carbon dioxide and water, which is known as photosynthesis, stores some of this chemical energy. Photoautotrophs are creatures that perform photosynthesis, including most plants, algae, and cyanobacteria. The majority of the energy required for life on Earth is produced and maintained by photosynthesis, which is also substantially responsible for producing and maintaining the oxygen content of the atmosphere.
As it absorbs carbon dioxide from the atmosphere and subsequently binds carbon in plants, soils, and harvested goods, photosynthesis is essential for climate processes.
