Q. Consider the following statements (A)–(D) each with one or two blanks.
A) (3) – expanding, (4) – commensalism, (5) – biodiversity park
B) (1) – hibernation, (2) – escape, (3) – expanding, (5) – hot spot
C) (3) – stable, (4) – commensalism, (5) – marsh
D) (1) – aestivation, (2) – escape, (3) – stable, (4) – mutualism
Explanation
[Solution from source] Bears hibernate to escape the cold winter, a broad-based conical age pyramid indicates an expanding population, and an area with very high species richness is a hotspot. Fig and wasp is mutualism, not commensalism, and a broad base means growth, not stability, so only the choice with hibernation, escape, expanding and hot spot fills its blanks correctly. Answer (2).
