Consider the following statements (A)-(D), each with one or two blanks.
(A) Bears go into (1) during winter to (2) cold weather.
(B) A conical age pyramid with a broad base represent (3) human population.
(C) A wasp pollinating a fig flower is an example of (4).
(D) An area with high levels of species richness in known as (5).

Which one of the following options, gives the correct fill ups for the
respective blank numbers from (1) to (5) in the statements.


(3) Expanding, (4) commensalism, (5) biodiversity park


(1) Hibernation, (2) escape, (3) expanding, (5) hot spot


(3) Stable (4) commensalism, (5) marsh


(1) Aestivation, (2) escape, (3) stable, (4) mutualism


  • Some animals undergo a long sleep or a temporary period of activeness to avoid extreme climatic conditions. Winter sleep is called hibernation and summer sleep is called aestivation. 
  • An age pyramid with a broader base indicates that there are a number of individuals present in the pre-reproductive phase to take place of the individuals in the reproductive phase.
  • Such a population is an expanding population. In case the number of individuals in pre-reproductive age are less than those in the reproductive phase, the population will be declining population.
  • If an area is characterized by an unusually high diversity of organisms, and most of them usually endemic; such an area will be called as biodiversity hot spot, like western Ghats in our country.
    Hence, the correct option is B.
