False

Explanation:

A forcible breaking up of the adhesions in an anklosis to allow more mobility in the joint is known as Arthroclasia.

It is not related to the therapeutic procedure in which involves the placing of the ankylosed joint in traction.

This techniques provides mobility to the joint which is clogged by the fusion of bones and can cause abnormal stiffness and immobility.

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.
