The atmosphere to various pools on the earth's surface

Explanation:

Human beings have dramatically altered the flux rate of nitrogen from the biosphere.

Explanation:

Human beings have greatly altered the nitrogen cycle or flow of nitrogen within the biosphere which consists of every place on Earth where living things exist: the land, water, and air. The major cause of this great alteration has been the improper disposal of organic matter, and combustion of fossil fuels which have polluted soils, air, oceans and other water bodies with nitric oxides, elements, and ions that lead to the formation of acid rain and smog, amongst other dangerous by-products.
