How is nitrogen returned to the atmosphere during the nitrogen cycle? a. It is returned to the atmosphere in a process called nitrogen fixation.
b. It is returned to the atmosphere through denitrification.
c. It is returned to the atmosphere through cellular respiration.
d. It is returned to the atmosphere through evapotranspiration.

Nitrogen is returned to the atmosphere during the nitrogen cycle through denitrification.

Nitrogen is cycled in nature from the atmosphere to living organisms and to the soil. The nitrogen cycle involves the means by which nitrogen is utilized and released in nature. The process that release nitrogen back to the atmosphere is called DENITRIFICATION. Denitrification is the process by which certain microbes in the soil convert nitrate and nitrite to atmospheric nitrogen.

Therefore, nitrogen is returned to the atmosphere during the nitrogen cycle through denitrification.

The answer is ozone layer.

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
