Question

1. why do you think carbon dioxide is important even though it makes up only 0.04% of the atmosphere?
2. if nitrogen and oxygen together make up 99% of the air, what does that tell you about the role of other gases?

Explanation:

4.

Carbon dioxide is crucial for photosynthesis, which is the process by which plants convert light energy into chemical energy. It also plays a role in the greenhouse effect, helping to maintain Earth's temperature suitable for life.

Since nitrogen and oxygen make up 99% of the air, other gases are present in trace amounts. But they still have important roles such as being involved in chemical reactions, affecting weather and climate, and being used in industrial processes.

Answer:

Carbon dioxide is important because it is essential for photosynthesis in plants and contributes to the greenhouse - effect that keeps the Earth warm enough to support life.
