|---|---|
| Process/terms related to ecosystem | Explanations |
| (A) Decomposition | (I) Highly resistant to microbial actions |
| (B) Humus | (II) Oxygen dependent process |
| (C) Stratification | (III) Break down of detritus |
| (D) Fragmentation | (IV) Distribution of species |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
(A) Decomposition — this matches (II) Oxygen dependent process. Decomposition is largely an oxygen-requiring process; it slows down when oxygen is lacking, as in waterlogged soil.
(B) Humus — this matches (I) Highly resistant to microbial actions. This dark amorphous substance decomposes at an extremely slow rate and works as a reservoir of nutrients.
(C) Stratification — this matches (IV) Distribution of species. It is the vertical layering of species at different levels, as trees, shrubs and herbs in a forest.
(D) Fragmentation — this matches (III) Break down of detritus. Detritivores such as earthworms break detritus into smaller particles.
