2) Terrestrial animals--Animals that live on the land are called terrestrial animals.e.g
lion, deer
3)
Aquatic animals--Animals
that live in water are called aquatic
animals.e.g fishes, crabs
4)
Amphibians--Some animals can live on land and in water, both. These animals are called amphibians.
Frogs and salamanders are amphibians.
5) Arboreal animlas—Terrestrial animals that spend most of their time on trees are called arboreal animals. Monkeys and chameleons

6) Aerial animals--Animals that can fly are called aerial animals. Birds and bats are aerial
animals.
7) Adaptation--Adaptation is the process of
changing one’s body features or eating
and living habits to adjust to the
environment.
8 )Camouflaging— Animals blend with their environment when they have the same
body color or pattern as their surroundings. This is called camouflaging
and it keeps them safe against predators.
Polar bears and camels camouflage with their habitats.
9) Migration--Some animals and birds migrate or move
in groups from one place to another seasonally. They travel long distances to avoid extreme weather conditions or in search of
favorable food and breeding grounds.
For example- in winters,
Siberian cranes migrate to India from Russia.
10) Hibernation-- During hibernation, these animals sleep in their burrows and
caves through the winter months. This helps them save energy and keeps their bodies
warm.
11) Echolocation-- The method by which animals locate objects by listening to
echoes is known as echolocation. Dolphins and bats use echolocation for
movement and communication.
12) Nocturnal animals--Animals which are active
during the night than day are called nocturnal animals
Q.2 Why do animals animals show
locomotion or movement?
Ans. Animals need to keep moving from one place to another in search
of food, water, shelter and to also protect themselves from predators.
Q.3 Write the function of the following body covering
·
Scales- Fish
and reptiles have scales on their bodies, which prevent water from entering.
·
Shell- It is
a hard outer covering that protects the
soft bodies of animals such as snails and tortoises.
·
Fur and wool-
It is a thick outer covering that protects animals like sheep and the Arctic
Fox from extreme cold and gives them
warmth.
·
Feathers-
They are light in weight and help
the birds to fly and keep their body
warm. These colorful feathers also help in camouflaging, mating and defence.
Q.4 Write the breathing adaptations
of fishes, frogs and insects.
Ans. In aquatic habitats, gills help blood absorb the oxygen present in
water.
Frogs breathe through lungs
when on land and through their skin when in water.
Insects have small air
holes called spiracles which lead to a network of tubes called trachea that
help in breathing. Birds have air sacs and lungs for breathing.
