Trees breath it in. Humans breath it in. So its in the air around us!
it is oxygen and/or carbondioxcide ( srry I didn't spell it correct )
no. the tree grows on sunlight and carbondioxcide (like a human but the opposite) and gets nutrition from the soil. :)
Carbon dioxide is abundant gas in atmosphere. Argon is found only in traces.
Oxygen is the gas that passes from the bloodstream to body cells through the process of oxygenation. Oxygen is essential for cellular respiration, which is the process that cells use to generate energy.
As of October 2023, atmospheric carbon dioxide (CO2) levels are approximately 420 parts per million (ppm), continuing an upward trend due to human activities like fossil fuel combustion and deforestation. This increase poses significant challenges for climate change, contributing to global warming and related environmental impacts. Monitoring CO2 levels is crucial for understanding and addressing climate change.
