A) bears generally go in winter sleep(hibernation) to escape from winter
b)if any age pyramid has broad base that represents earlier population is greater i.e expanding.
c) a wasp pollinating fig flower is an example of mutualism not of commensalism.
D) an area with high level of species diversity is called as hotspot
so option B is correct.
Consider the following statements : (A)- (D) each with one or two blan...
The correct fill-ups for the respective blanks in the given statements are:
(A) Bears go into (1) hibernation during winter to (2) escape cold weather
(B) A conical age pyramid with a broad base represents (3) expanding human population
(C) A wasp pollinating a fig flower is an example of (4) mutualism
(D) An area with high levels of species richness is known as (5) biodiversity hotspot
Let's understand each statement and its correct fill-ups in detail:
(A) Bears go into (1) hibernation during winter to (2) escape cold weather:
- Hibernation is a state of inactivity and metabolic depression that animals enter during the winter months.
- Bears go into hibernation to survive the cold weather when food sources are scarce.
- Therefore, the correct fill-ups for the blanks are "hibernation" and "escape."
(B) A conical age pyramid with a broad base represents (3) expanding human population:
- An age pyramid is a graphical representation of the age and sex distribution of a population.
- A conical age pyramid with a broad base indicates a high proportion of young individuals in the population.
- This suggests that the population is expanding because there are more individuals in the younger age groups.
- Therefore, the correct fill-up for the blank is "expanding."
(C) A wasp pollinating a fig flower is an example of (4) mutualism:
- Mutualism is a type of symbiotic relationship in which both species involved benefit from each other.
- In the case of a wasp pollinating a fig flower, the wasp benefits by obtaining food (nectar) from the flower, while the flower benefits from the wasp's pollination services.
- Therefore, the correct fill-up for the blank is "mutualism."
(D) An area with high levels of species richness is known as (5) biodiversity hotspot:
- A biodiversity hotspot is a region that has a significant concentration of species diversity, both in terms of species richness and endemism.
- These hotspots are characterized by high levels of species richness and are of significant conservation value.
- Therefore, the correct fill-up for the blank is "biodiversity hotspot."
In conclusion, the correct fill-ups for the respective blanks in the given statements are (B) hibernation, escape, (B) expanding, (C) mutualism, and (D) biodiversity hotspot.
