Anatomy and physiology: Your friend Jared works a highly stressful job as an air traffic controller. His diet during his shift consists mainly of candy bars and sodas. He has been sick more often and jokingly exclaims to you that his job is “aging him prematurely.” Your response to Jared is that this may not be far from the truth. Why?

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
