True or False: Carbon is present in the air.

The statement is true because carbon is indeed present in the air, primarily in the form of carbon dioxide (CO2). Carbon dioxide is a critical component of the Earth's atmosphere and plays an essential role in processes like photosynthesis and the greenhouse effect. While carbon is not abundant in gaseous form compared to nitrogen or oxygen, its presence in the atmosphere is significant for maintaining life on Earth and regulating climate. Thus, the assertion that carbon is present in the air aligns with the understanding of atmospheric composition.

In discussions about carbon presence, it's important to note that while it may exist in lower concentrations compared to other gases, its impact and functions are vital within ecological and biochemical contexts.
