Identify the correct statements:
A. Detrivores perform fragmentation
B. The humus is further degraded by some microbes during mineralization.
C. Water soluble inorganic nutrients go down into the soil and get precipitated by a process called leaching.
D. The detritus food chain begins with living organisms.
E.Earthworms break down detritus into smaller particles by a process called catabolism.
Choose the correct answer from the options given below:
A, B, C only
Correct answer: Option B – A, B, C only
Explanation:
Statement A is correct because detritivores, such as earthworms, perform fragmentation, breaking detritus into smaller particles and increasing the surface area for microbial action.
Statement B is correct since humus, formed during decomposition, is further degraded by microorganisms during the process of mineralisation, leading to the release of inorganic nutrients.
Statement C is also correct because leaching involves the downward movement of water-soluble inorganic nutrients into the soil horizons, where they may get precipitated as unavailable salts.
Statement D is incorrect as the detritus food chain begins with dead organic matter, not living organisms.
Statement E is incorrect because earthworms carry out fragmentation, not catabolism; catabolism is performed by microbial enzymes.
Thus, the correct set is A, B, and C → Option B.
