Detailed explanation-1: -So, the correct option is “D” (Photosynthesis).

Detailed explanation-2: -Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Detailed explanation-3: -New research has found that between 1982 and 2020, global plant photosynthesis grew 12 percent, tracking CO2 levels in the atmosphere as they rose 17 percent. The vast majority of this increase in photosynthesis was due to carbon dioxide fertilization. Increased photosynthesis results in more growth in some plants.

Detailed explanation-4: -Studies have shown that increased concentrations of carbon dioxide increase photosynthesis, spurring plant growth. While rising carbon dioxide concentrations in the air can be beneficial for plants, it is also the chief culprit of climate change.
