Answer 1

$\huge\bf{Answer:-}$

carbon dioxide it's chemical formula CO2, is a colorless and odorous gas that is essential for life on Earth. It is found naturally on the earth. This gas is about 0.03 percent by volume in the Earth's atmosphere. Carbon dioxide is composed of two atoms of oxygen and one atom of carbon. It remains in gaseous state at normal temperature and pressure.

This gas is found in the atmosphere from 0.03% to 0.04%, but its concentration in the air also changes slightly as the weather changes. It is a greenhouse gas, because the rays coming from the sun are on the earth's surface. But when the heat of the Earth wants to go back to space, it stops it.

It is Used for breathing for plants and trees.
