Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Nitrogen Fixation is the part of the nitrogen cycle that is involved in moving nitrogen from the atmosphere into the soil.
<u>Explanation:</u>
- Nitrogen is said to be an essential one in the atmosphere but even though it exists as inactive in the atmosphere it is converted as usable nitrogen by the cycle.
- The nitrogen cycle is considered to be one of the important factors for the survival of the plants. Nitrogen is not used directly in photosynthesis by the plants whereas it is converted to nitrate by the help of nitrogen-fixing bacteria in the soil.
- Thus the nitrogen fixation process converts nitrogen into ammonium ions and then it is used by the plants.
