When a blood vessel is damaged, the fibers within the connective tissue beneath the endothelial cells in the vessel wall become exposed. Platelets adhere to these fibers with the assistance of a plasma protein called . As the platelets start to stick to the vessel wall, their morphology changes dramatically. They develop that further adhere them t

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.
