2. Read the paragraph and the
following questions
I am a penguin. I live in polar region
covered by snow. My abdomen
white. My skin is thick with a layer of
fat underneath. My body is spindle
shaped. My wings are small. My toes
are webbed. We live in Blocks
(a) Why is my skin white and thick
and why is there a thick layer of
fat underneath
(6) Why do we live in flocks sticking
close to each other?
(c) Which geographical region do
inhabit? Why
(4) Which adoptations should you have
to enable you to live permanently
Answers
Answer:
a) a. Having black and white skin is a type of adaptation known as camouflaging. It is called counter-shading and makes it harder for both the predators and the prey to see penguins from all sorts of angles. The white chest of penguin protects them in the water by camouflaging them from being seen from below against the lighter sky coming through the waters surface. Their black backs help them blend in with the darker, deeper ocean waters below them, thus protecting them from their predators. They have thick layer of fat because it keeps them warm under such extreme cold conditions.
b. We know that penguins live in the coldest regions of earth and in order to find warmth and solace they remain in flocks with each other. In order to escape the extreme cold conditions, they nestle together to keep each other warm.
c. Penguins are found in regions of Antarctica, South America, Africa and Australia. Many species can also be found in New Zealand and the sub-Antarctic islands.
d. The following adaptations are required to survive in polar regions:
black and white skin with a thick layer of fat beneath it
skin should be covered with feathers
small body with small wings
presence of strong muscles in chest and wings
Explanation:
Answer:
(a) Penguin's skin is white so that it can mix with the surrounding and cannot be easily located. In this way it seeks protection against predators has thick skin with a thick layer of fat underneath because it does not allow the body heat escape out.
(b) Penguins stay in flocks hence they would get protection from predators. Also sticking to each other the body heat is not lost the surrounding.
(c) Penguin stay in polar region especially in the Antarctic region. There is abundant food available for the Penguins and thus they are seen there.
(d) In order to inhabit permanently in the polar region, the body should be adapted to cold temperature. There should be thick layer of fat and thick skin to protect the body. The ability to regulate body temperature should be extremely good for the survival.
