Answer:
The nitrogen cycle could not exist without the presence of nitrogen-fixing microorganisms.
Explanation:
As part of the biogeochemical cycles that occur in nature, the nitrogen cycle involves all the organic and non-organic processes that allow the incorporation of this element into the organism of living beings.
Although nitrogen is abundant in nature, in gaseous form, living beings cannot take advantage of it, because they lack the ability to convert this gas into organic nitrogen. Nitrogen-fixing microorganisms -such as bacteria in the soil- turn inorganic nitrogen into organic, that incorporates plants.
Nitrogen-fixing bacteria exist in both soil and plant roots. They are responsible for the conversion of atmospheric nitrogen and ammonium, the product of the degradation of organic matter, into nitrites and nitrates that assimilate the plants. Herbivorous animals obtain this nitrogen from vegetables, and carnivores from them.

All things that are living are made of cells.
How much carbon dioxide is produced when different fuels are burned?
Different fuels emit different amounts of carbon dioxide (CO2) in relation to the energy they produce when burned. To analyze emissions across fuels, compare the amount of CO2 emitted per unit of energy output or heat content.
Pounds of CO2 emitted per million British thermal units (Btu) of energy for various fuels:
<span><span> Coal (anthracite) 228.6</span><span> Coal (bituminous) 205.7</span><span> Coal (lignite) 215.4</span><span> Coal (subbituminous) 214.3</span><span> Diesel fuel and heating oil 161.3</span><span> Gasoline 157.2</span><span> Propane 139.0</span><span> Natural gas<span> 117.0</span></span></span>
