Q. What are the differences in the desert and sea regions?
Ans. In the sea, plants and animals are surrounded by salty water. Most of them use the air dissolved in water for breathing. In desert, a very little amount of water is available. It is very hot in the day time and very cold at night. The organisms breathe air from the surroundings.
Q. How are some animals adapted to live in desert?
Ans. Some animals like rats and snakes do not have the long legs like camels to stay away from the effect of heat during the day. They stay in burrows deep in the sand. They come out only during the night.
Q. How are camels adapted to live in desert?

(e) The long legs of camel helps to keep the body away from the heat of the sand.
Q. How camels keep their bodies away from the heat of sand.
Ans. They have long legs that keep their body away from the hot sand. Due to their long legs, their body remains at a fair distance from the sand.
Q. Why do desert snakes burrow deep into the sand during the day?
Ans. As the deeper layers of sand are cooler, they burrow deep into the sand to stay away from heat of the desert during day time.
Q. Write the features of desert plants.
Ans.
(a) The leaves in desert plants are either absent or very small.
(b) Leaves are converted into spines which help to reduce loss of water.
(c) The stems become thick, flat and green which help in photosynthesis.
(d) The stem is covered with waxy layer which helps to retain water. In some plants stem is spongy and stores water.
(e) The roots go very deep in the soil to absorb water.
Q. Write any two adaptive features of cactus plant.
Ans. A cactus has special adaptations in its roots, leaves as well as stems that enable it to thrive in desert environments. These adaptations include – spines, shallow roots, deep-layer stomata, thick and expandable stem, waxy skin and a short growing season.
Q. Desert plants have long roots spreading into the soil.
Ans. In desert there is less of rainfall we all know. In case it would be great depth of water levels. Hence to get the water stored and supply it to other parts, the roots of plants that grow in desert, are very deep into the soil.
Q. Some desert plants have very small leaves whereas some others have only spines. How does this benefit the plants?
Ans. Some of the desert plants have very small leaves whereas some have only spines to reduce water loss through the process of transpiration. This adaptation helps the plants to conserve water.
Q. How do rats and snakes escape from the intense heat of desert?
Ans. Snakes and rats in the desert burrow under the soil to escape the scorching heat of the sun.
Q. What are the adaptive features of a lion that helps it in hunting?
Ans.
(a) Brown body colour helps it to hide in dry land avoiding detection by its prey.
(b) Eyes placed in front allow it to know the exact location and movements of its prey.
(c) Powerful paws and long claws help it to catch and kill the prey.
Q. What are the specific features present in a deer that helps it to detect the presence of predators like lion?
Ans.
(a) A deer has long ears to hear movements of predators.
(b) The eyes present on the sides of the head enable it to look in all directions.
(c) The deer runs at a high speed that helps it to escape predators. All these features helps the deer to detect the presence of predators.
Q. Why Tigers have eyes in front, how is it an adaptive feature? Is it behavioral or structural adaptation?
Ans. Tigers have forward facing eyes rather than one on each side of their head. This provides binocular vision because each eye's field of vision overlaps creating a three-dimensional image. It is a structural adaptation.
Q. Explain the features of fish which help it to adapt to live in water.
Ans.
(a) The shape of the fish is streamlined which help in the movement.
(b) The slippery scales/skin on their bodies to protect them.
(c) They have flat fins and tails which help them to swim, change direction and to keep the body balanced.
(d) They have gills which help in breathing in water.
Q. Why Whales and dolphins have blowholes?
Ans. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads. This allows them to take breaths by exposing just the top of their heads to the air while they are swimming or resting under the water.
Q. Frogs can live both on land and in water, name the adaptations seen in these animals.
Ans. Frogs have strong back legs that help them in leaping and catching their prey. They have webbed feet which help them to swim in water.
Q. Explain the adaptation of plants to live in water.
Ans.
(a) Roots are reduced in size which hold the plant.

(b) plants release oxygen gas in photosynthesis which is used by animals for respiration.
(c) animals release carbon dioxide which is used by plants for photosynthesis.
Q. What do you mean by acclimatization?
Ans. The small changes which take place in the body of a single organism over short periods to overcome small problems due to changes in the surroundings are called acclimatization.
Q. What is camouflage? How is it an adaptive feature?
Ans. Camouflage is an adaptation that helps an organism blend in with its surroundings. Blending in helps the animal avoid predators and increases its ability to survive. Organisms may use their ability to blend in for different reasons, but ultimately it helps an animal to survive and reproduce.
Q. Like many animals a car also moves, but it is not considered as a living organism. Why?
Ans. Living organisms move on their own, but Car moves by the burning of fuels like diesel and petrol.
also Car does not show any other living characteristics like respiration, digestion, reproduction & growth.
Q. If Sunlight is essential for photosynthesis, then how will aquatic plants survive?
Ans. The aquatic plants get the sunlight essential for photosynthesis inside the water because water is a transparent medium so it allows light to pass through it and reach the plants.
Q. What kind of movement do we see in plants?
Ans.
(a) Opening and closing of a flower.
(b) Growth of a stem and leaves.
(c) Movement of water, minerals and food from one part of the plant to other.

Q. What may happen if :
a) A fish is taken away from water and placed on land.
Ans. If a fish is taken away from water and placed on land it will die due to the absence of oxygen because the gills can obtain oxygen only from water.
b) An insect living in soil placed in pond.
Ans. If an insect living in soil placed in pond it will not able to survive because it will not able to breath inside water.
