Match the Component of the Nitrogen Cycle with Its Description

Question 18

Matching

Match the component of the nitrogen cycle with its description.

Premises:

Responses:

converts N₂ to NH₃

nitrogen fixation

carried out by nitrifying bacteria

denitrification

the process by which animals convert plant nitrogen compounds into animal nitrogen compounds

nitrification

this process occurs in root nodules

assimilation

Rhizobium carries out this process

converts nitrate to gaseous nitrogen

returns gaseous nitrogen to the atmosphere

the process by which roots incorporate nitrogen into proteins, nucleic acids, and chlorophyll

the principle enzyme is nitrogenase

converts NH₃ to NO₃^-

this process occurs in heterocysts
