Question

Inorganic nutrients are released into the soil by the decomposition of dead organic matter through a process called as ________

• A. Photosynthesis
• B. Mineralization
• C. Purification
• D. Respiration

Hint:

Microbes turn humus into mineral nutrients: mineralization.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
We want the name of the process that gives inorganic nutrients from dead matter.

Step 2: Follow the chain:
Dead matter goes to humification, then humus goes to mineralization.

Step 3: Name the last step:
The last step gives out mineral nutrients, so it is mineralization.

Step 4: Reject photosynthesis:
It builds organic matter instead of breaking it down.

Step 5: Reject respiration and purification:
Respiration frees energy and purification is not a soil step.

Step 6: Match:
Option 2.

Final Answer:
\[\boxed{2}\]
