Carbon dioxide fluctuations occur for different seasons of the year due to the presence of plants in an area.
<h3>Why carbon dioxide fluctuations occur for different seasons of the year?</h3>
The carbon dioxide levels in the atmosphere moves up and down every year when plants use carbondioxide gas through the process of photosynthesis and respiration. Plants take up the carbondioxide gas in the spring and summer season and release it in fall and winter season. In this modern world, the level of carbon cycle is increasing because more carbon dioxide is emitted from burning fossil fuels and other human activities.
So we can conclude that carbon dioxide fluctuations occur for different seasons of the year due to the presence of plants in an area.
