The answer is - it can not be taken out of the atmosphere.
The nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both, humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.

Answer:
Five factors that affect climate:
Explanation:
These factors are the most important factors that affect the Climate of a region.
Ocean currents: the ocean currents moves warm water and precipitation from the equator towards the pole and it also moves cold water from the poles back to the tropics, this action helps to regulate the climate
Topography : the shape of the land affects the climate like for places with hills or mountains the climate there is usually harsher than low lands because the hills obstruct the free flow of air and rain clouds.
latitude : places closer to the equator have warmer climate conditions considered to places at the poles.
distance from sea: areas closer to the sea have cooler climate conditions than ares farther from the seas, warm winds from inland mix up with cool airs to form clouds.
prevailing winds: warm air travelling across water collects moisture and takes it to the coastal areas where they are condensed and later fall as rain.
