Class 7 Science - Chapter Weather, Climate and Adaptations of Animals to Climate NCERT Solutions | Following are some of the characteristic
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?
(i) Diets heavy on fruits - Tropical
Due to the heavy rainfall and moderate temperature, the quality of the fruits is good. That's why the birds feeds on fruit.
(ii) White fur - Polar region
The organisms who lives in polar region have white furs which protects them from the extreme conditions of environment and protects them from the prey because they look like the snow.
(iii) Need to migrate - Polar region
This characteristic shown by the organisms that lives in the polar region. They migrate towards the lower region that contains moderate and average temperature from the excessive cold conditions for the survival.
(iv) Loud voice - Polar region and Tropical rainforest
This characteristic is shown by both the regions polar and tropical. This characteristic is used to call the mates and to capture the prey by showing the groupism attack.
(v) Sticky pads on feet - Polar region
Sticky pads are used by the polar region organisms. This characteristic is used to make the grip on the snow.
(vi) Layer of fat under skin - Polar region
This characteristic is adapted by the organisms which lives in the polar region. These organisms contains layer of fat under the skin to protect themselves form the excessive cold conditions.
(vii) Wide and large paws - Polar region
These characters are adapted in the polar regions by the organisms who lives there. They contain these charaters to make the grip and for the easy movement pattrens in the snow.
(viii) Bright colours - Tropical
These characteristics are adapted by the organisms that lives in the tropical rainforest which is also known as evergreen forest. Bright colours are shown by the organisms to attract the mates and the animal pollinators for proceeding the process of pollination.
(ix) Strong tails - Tropical
Strong tails are adapted in the tropical region by the organisms that lives there. Strong tails are used to capture the prey.
(x) Long and large beak - Tropical
This characteristic is adapted by the birds of tropical region. This characteristic helps the birds to feed on the hard shelles nuts and seeds or to capture the insects.
