Answers (1)
The correct option is Option 1) A, B, C only.
(A) Detrivores perform fragmentation. This statement is correct. Detrivores are organisms that break down organic matter into smaller particles through fragmentation, facilitating the decomposition process.
(B) The humus is further degraded by some microbes during mineralization. This statement is correct. Humus, the partially decomposed organic matter, undergoes further degradation by microbes during the process of mineralization, where organic compounds are converted into inorganic forms.
(C) Water-soluble inorganic nutrients go down into the soil and get precipitated by a process called leaching. This statement is correct. Leaching is the process by which water-soluble inorganic nutrients are washed down through the soil profile and can get precipitated or accumulate in deeper layers, affecting nutrient availability.
(D) The detritus food chain begins with living organisms. This statement is incorrect. The detritus food chain begins with dead organic matter, such as fallen leaves or dead animals. It involves the decomposition and consumption of detritus by organisms.
(E) Earthworms break down detritus into smaller particles by a process called catabolism. This statement is incorrect. Earthworms break down detritus into smaller particles through a process called physical fragmentation or grinding, not catabolism.
Therefore, Option 1) A, B, C only is the correct choice.
