Explanation:

Nitrogen cycle is one of the important biogeochemical cycle.

Nitrogen is an ingredient for synthesis of aminoacids which are necessary for production of plant proteins. But plants are incapable of absorbing the atmospheric nitrogen directly. Certain soil bacteria convert the atmospheric nitrogen into forms like nitrites, nitrates and ammonia. This process is called as nitrogen fixation. These forms are absorbed by plants and the bacteria receives nourishment from roots of the plants.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.
