Question 5
Which of the two changes frequently, weather or climate?
Weather changes frequently.

Question 6
Following are some of the characteristics of animals:
(i) Diets heavy on fruits
(ii) White fur
(iii) Need to migrate
(iv) Loud voice
(v) Sticky pads on feet
(vi) Layer of fat under skin
(vii) Wide and large paws
(viii) Bright colours
(ix) Strong tails
(x) Long and large beak
For each characteristic indicate whether it is adaptation for tropical rainforests or polar regions. Do you think that some of these characteristics can be adapted for both regions?
Diets heavy on fruits
Tropical rainforests
White fur
Polar regions
Need to migrate
Polar regions
Loud voice
Tropical rainforests
Sticky pads on feet
Tropical rainforests
Layer of fat under skin
Polar regions
Wide and large paws
Polar regions
Bright colours
Tropical rainforests
Strong tails
Tropical rainforests
Long and large beak
Tropical rainforests

No, these characteristics can't be adapted for both regions as they are specific.

Question 7
The tropical rainforest has a large population of animals. Explain why it is so.
The tropical rainforest has a large population of animals due to many reasons
(a) Climate is hot and gets plenty of rainfall. Because of continuous warmth and rain, this region supports wide variety of plants and animals.
(b) The region being near to equator, receives more solar energy available. It contributes to higher productivity in terms of food and population.
(c) Tropical rainforest remained less disturbed for millions of years, thus giving longer time to evolution. It resulted in wide variety of species.

Question 8
Explain, with examples, why we find animals of certain kind living in particular climatic conditions.
We find animals of certain kind living in particular climatic conditions because every living organism are adapted to live in the particular habitat. Every living thing develop their feature according to the adaption area.
For example, penguins have thick skin to protect themselves from cold and webbed feet to swim in water. It can't able to survive the hot climate of tropical regions as they developed thick skin for the protection from cold not from the hot and humid temperature. Another example would be of Monkeys. They have long tails for grasping branches adapted to live in tropical rain forests. It cannot survive in polar regions.

Question 9
How do elephant living in the tropical rainforest adapt itself?
Elephant living in the tropical rainforest are well adapted itself to this region.
(i) They have strong sense of smell and uses its trunk for smell.
(ii) Also trunk is used to hold food.
(iii) They have long ears which help them in keeping cool in hot and humid climate.
(iv) Long ears also help them in hearing very soft sound.
(v) They have thick padded feet which help them in moving silently.

Question 10
A carnivore with stripes on its body moves very fast while catching its prey. It is likely to be found in
(i) polar regions (ii) deserts
(iii) oceans (iv) tropical rainforests
(iv) tropical rainforests

Question 11
Which features adapt polar bears to live in extremely cold climate?
(i) A white fur, fat below skin, keen sense of smell.
(ii) Thin skin, large eyes, a white fur.
(iii) A long tail, strong claws, white large paws.
(iv) White body, paws for swimming, gills for respiration.
