(ii) A conical age pyramid with a broad base represents 3_________ human population.

(iii) A wasp pollinating a fig flower is an example of 4________.

(iv) An area with high levels of species richness is known as 5_________.

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

• A. 3 - expanding, 4-commensalism, 5 - biodiversity park
• B. 1 - aestivation, 2 - escape, 3 - stable, 4 - mutualism
• C. 1- hibernation, 2 - escape, 3 - expanding, 5 - hot spot
• D. 3 - stable, 4 - commensalism, 5 - marsh

Answer 1

The correct option is C 1- hibernation, 2 - escape, 3 - expanding, 5 - hot spot

Hibernation

Hibernation is a state of prolonged inactivity by sleeping during the winters.

For example, bears go into hibernation (1) during winter to escape (2) from the cold weather.

Age pyramid of expanding population

The population pyramid shows larger numbers or percentages of the population in the pre-reproductive age groups (broad base), relatively fewer individuals in the reproductive age group and the least number of individuals in the post-reproductive age group represents the expanding (3) age pyramid of population.

Hot Spots

Hot Spots (5) refer to the area with high density of diversity or mega diversity which are threatened at present.

Final answer
(b) 1- hibernation, 2 - escape, 3 - expanding, 5 - hot spot
