Question

How many steps are involved in the process of decomposition?

(a) 10

(b) 2

(c) 8

(d) 5

I had been asked this question during an internship interview.

My doubt stems from Ecosystem in section Ecosystem of Biology – Class 12

Answer 1

The correct answer is (d) 5

The best I can explain: The physical and chemical process of break down complex organic remains (dead or decaying organisms) into inorganic substances is called decomposition. The decomposition is a 5 step process. The steps are fragmentation, leaching, catabolism, humification, and mineralization respectively.
