Question

Give 2 ways carbon dioxide gets into the air?

Answer 1

Atmospheric carbon dioxide comes from two primary sources—natural and human activities. Natural sources of carbon dioxide include most animals, which exhale carbon dioxide as a waste product. Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.

Answer 2

We breathe our carbon dioxide, so do plants. Animals and plants get rid of carbon dioxide gas through a process called respiration.
