Question

Which of the following accurately describes the role of ammonification in the nitrogen cycle?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Nitrogen cycle
 **Related Topics**: Biogeochemical cycles, decomposition, nitrogen fixation, nitrification, denitrification
 **Prerequisites**: Understanding of the different forms of nitrogen and the roles of various microorganisms in the nitrogen cycle.
## SOLUTION PATHWAY
**Given Information**:
The question asks about the role of ammonification in the nitrogen cycle.
**Method & Steps**:
1. Understanding the Nitrogen Cycle: The nitrogen cycle describes the process by which nitrogen is converted between different chemical forms.  Key processes include nitrogen fixation, ammonification, nitrification, and denitrification.
2. Defining Ammonification: Ammonification is the process where organic nitrogen-containing compounds (like proteins, nucleic acids, and urea) are broken down into ammonia ($NH_3$) by decomposers (bacteria and fungi).
3. Analyzing the options:
    * Option A describes nitrogen fixation.
    * Option B describes nitrification.
    * Option C accurately describes ammonification.
    * Option D describes denitrification.
4. Selecting the correct answer: Option C correctly defines ammonification.

Result: C
 Verification: The definition of ammonification aligns perfectly with option C.
 ## OPTION ANALYSIS
A :x: This describes nitrogen fixation, where atmospheric nitrogen ($N_2$) is converted to ammonia ($NH_3$) by nitrogen-fixing bacteria.
B :x: This describes nitrification, where ammonia ($NH_3$) is converted to nitrites ($NO_2^-$) and then nitrates ($NO_3^-$) by nitrifying bacteria.
C ✓: This accurately describes ammonification, the process by which decomposers convert organic nitrogen into ammonia.
D :x: This describes denitrification, where nitrates ($NO_3^-$) are converted back to atmospheric nitrogen ($N_2$) by denitrifying bacteria.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing ammonification with nitrogen fixation or nitrification: Understanding the specific substrates and products of each process is crucial to avoid this mistake.
  2.Not recognizing the role of decomposers:  Remembering that ammonification is carried out by decomposers (bacteria and fungi) is key.
 **Quick Tips**:
  1.Use mnemonics or diagrams to remember the different steps in the nitrogen cycle and the roles of different microorganisms.
  2.Focus on the reactants and products of each step to differentiate between the various processes.
