Oxygen A+
Most of the nitrogen on Earth is found in the atmosphere, making up about 78% of the air we breathe. Nitrogen is also present in the soil and in living organisms as a vital component of proteins and DNA.
No, oxygen is a non-metallic element and is not considered alkaline. Oxygen is a component of the air we breathe and is essential for most living organisms for respiration.
Nitrogen is a major component of the Earth's atmosphere, making up about 78% of the air we breathe. It is also an essential element in living organisms, as it is a key component of proteins, DNA, and other biological molecules. Additionally, nitrogen is found in fertilizers and is important for plant growth.
We breathe in approximately 78% nitrogen, which makes up the majority of the air we inhale. Nitrogen is an essential component of the Earth's atmosphere and is necessary for various biological processes in our bodies.
The most abundant gas in the air we breathe is nitrogen, which makes up about 78% of Earth's atmosphere. Oxygen is the second most abundant gas, making up about 21%.
Nitrogen (78.094%)
these ??? There are no choices to choose from.
Oxygen is a component of the Earth's atmosphere. It makes up about 21% of the air we breathe.
The most important aspect of air is that it keeps humans and animals alive. The air contains the oxygen that we need to breathe.
78% nitrogen 20.5% oxygen

it's oxygen !!!!!!!!!!!!!!!!!!!!!!!!!!!!
For humans and other animals, the oxygen in the air that we breathe is essential for life. When we breathe the air, our body uses the oxygen in it to enable the body to carry out the necessary processes for living.
No, oxygen is a non-metallic element and is not considered alkaline. Oxygen is a component of the air we breathe and is essential for most living organisms for respiration.
CO2 (Carbon Dioxide) for the most part, but the components of the original air that was inhaled are still present, although the O2 (oxygen) component will be reduced.
oxygen
"Air" is the most important cycle that exists between the atmosphere and earth, e.g. a sustained cycle between plants on earth and the air we breathe, and humans. Air is important as a natural resource because we AND plants must breathe. Plants use carbon dioxide which humans breathe out. Humans breathe in oxygen, which plants give off. Without these two components of "air" or if these became out of balance, both plants and humans would die.
