Which of the following processes occurs during decomposition in soil?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Humification.
The correct answer is Humification. During decomposition in soil, complex organic matter from dead plants and animals is broken down by microorganisms. One of the key processes in this breakdown is humification, where the decomposed organic material is transformed into humus—a stable, dark, and nutrient-rich substance. Humus improves soil fertility and structure. While oxidation may also occur as part of the overall decomposition, humification specifically refers to the formation of humus, making it the most relevant process among the given options.
