Nitrogen Cycle (2)

In this article we will discuss Nitrogen Cycle (2)

When the plant or animal dies, decomposing bacteria and fungi cause the body to decay so that the nitrogen-containing amino acids are broken down, releasing ammonia gas (NH3). Nitrite bacteria can convert the ammonia into nitrite (NO2) molecules, and still other bacteria (nitrate bacteria) in the soil can add a third oxygen atom to nitrites to produce nitrates.
