Question : Detritivores in the soil break down detritus into smaller particles. This process is called ______.
Option 1: catabolism
Option 2: mineralisation
Option 3: fragmentation
Option 4: leaching
Correct Answer: fragmentation
Solution : The correct answer is fragmentation.
The decomposition of detritus involves decomposers breaking down complex organic matter into inorganic substances. The key steps in this process include fragmentation, where detritus is physically broken into smaller pieces; leaching, where soluble substances are washed away; catabolism, involving the breakdown of complex organic compounds; humification and mineralization, where organic substances are converted into inorganic forms, enriching the soil with essential nutrients.
