Answer 1

The percentage of carbon dioxide in the atmosphere is 0.038.

Explanation:

Carbon dioxide makes up about 0.038% of the atmosphere by volume. Though present in small amounts, it plays a crucial role in the greenhouse effect and is important for processes like photosynthesis. The major gases in the atmosphere are nitrogen (approximately 78%) and oxygen (about 21%), while carbon dioxide is a minor but significant component.
