Vedclass · Answer

(B) The process of decomposition of organic nitrogenous compounds (found in dead plants and animals) into ammonia is known as $Ammonification$. $1$. $Ammonification$: Bacteria like $Bacillus$ and $Actinomycetes$ break down organic nitrogen into ammonia $(NH_3)$. $2$. $Nitrification$: Ammonia is further oxidized to nitrite $(NO_2^-)$ and then to nitrate $(NO_3^-)$ by bacteria like $Nitrosomonas$ and $Nitrobacter$. $3$. $Mineralisation$: This is a broader term referring to the release of inorganic nutrients from organic matter. $4$. $Humification$: This is the process of formation of dark-colored amorphous substance called humus from organic matter.
