**carbon dioxide**

Carbon dioxide (CO₂) is a colorless, odorless gas that is a natural component of the Earth’s atmosphere. It is produced by the respiration of animals and humans, the decomposition of organic matter, and the combustion of fossil fuels. Carbon dioxide plays a crucial role in the carbon cycle and is essential for photosynthesis in plants. However, elevated levels of CO₂ due to human activities contribute significantly to global warming and climate change by enhancing the greenhouse effect.
