(b) tropical region
(c) polar region
(d) coastal region
Soln:
The answer is (b) tropical region
Explanation:
The Wildlife sanctuary which Paheli went to was in a tropical region because this region has favourable conditions to support a wide variety of living organisms. The remaining options, like the temperate region, polar and coastal region, will not support a variety of wildlife as a tropical region.
5. Given below are some adaptive features of animals:

Like polar bears, penguins are also good swimmers. Their bodies are streamlined and their feet have webs, making them good swimmers.
7. Read the following environmental conditions of tropical rainforests.
(i) A hot and humid climate
(ii) Unequal lengths of day and night
(iii) Abundant rainfall
(iv) Abundant light and moisture
Identify the conditions from the above list that are responsible for the presence of large number of plants and animals in tropical rainforests.
(a) (i) and (ii)
(b) (i) and (iii)
(c) (i), (iii) and (iv)
(d) (ii) and (iv)
Soln:
Answer is (c) (i), (iii) and (iv)

During hot summers, the temperature may cross 40°C. Days and nights are almost equal in length throughout the year. These regions get plenty of rainfall. Because of these reasons, tropical rain forests support a large number of plants and animals.
8. The coldest region on earth is the –
(a) polar region
(b) tropical region
(c) temperate region
(d) coastal region
Soln:
The answer is (a) polar region
Explanation:
Polar regions are covered with snow, and it is very cold for most part of the year. For six months, the sun does not set at the poles, while for the other six months the sun does not rise. In winter, the temperature can be as low as –37°C.
