Question 1
1 / -0

Which of the following regions is not a terrestrial habitat?

A
Desert

B
Grassland

C
Lake

D
Forest

Solution

Habitat of animals and plants in different regions depends upon their body structure and its adaptability. For example, animals like yak, lions and ants live on ground and are known as terrestrial animals. Forests, grounds, grasslands and deserts are all included in the terrestrial habitat, whereas ponds, lakes, rivers, sea and ocean in the aquatic habitat.
Question 2
1 / -0

Plants belong to biotic components, whereas sunlight and air belong to

A
adaptation

B
habitat

C
living components

D
abiotic components

Solution

Different kinds of plants are found in different regions because of the reason that survival of different plants in a particular area depends upon many factors like climate, soil texture, organisms found over there, etc. All these factors are collectively divided into two major categories; the living components are called biotic and the non-living components are called abiotic components. Thus, sunlight and air are the abiotic components.
Question 3
1 / -0

Which habitat is characterised by hot and dry places?

A
Terrestrial

B
Arboreal

C
Xeric

D
Aquatic

Solution

Different places are having different climatic conditions and thus variety of flora and fauna. For example, terrestrial habitat refers to grounds, grasslands, etc. Arboreal refers to staying on trees like monkeys. Xeric refers to deserts having hot and dry climatic conditions and aquatic refers to water bodies.
Question 4
1 / -0

Which of the following is the characteristic feature of xerophyte stem?

A
Thick and waxy

B
Tender

C
Weak

D
Hard

Solution

Xerophytes are the plants growing in hot and dry places. For example, cactus is a plant that grows in deserts. Thus, to avoid the loss of excess water through stomata, its leaves are reduced to spine-like structures and it is the stem in these plants, which is green in colour and performs the functions of photosynthesis. Also, their stem is thick and waxy to prevent the loss of water.
Question 5
1 / -0

Which of the following sets belong to deserts?

A
Opuntia, Camel, Pine

B
Yak, Cow, Rat

C
Cactus, Babool, Camel

D
Hydrilla, Snake, Fish

Solution

Yak and cow are the terrestrial animals. Hydrilla and fish are the aquatic organisms. So, it is cactus, babool and camel which are the organisms belonging to deserts.
Question 6
1 / -0

Which of the following organisms is not a habitant of mountains?

A
Himalayan ibex

B
Snow leopard

C
Cow

D
Yak

Solution

Himalayan ibex, snow leopard and yak are the animals whose bodies are well adapted to habitat mountainous regions; but cow is an animal which lives on the ground or the grassland with a moderate temperature range and cannot survive on mountains.
Question 7
1 / -0

Grasses, zebra, lions and giraffes are the components of which of the following habitats?

A
Arboreal

B
Grassland

C
Desert

D
Marine

Solution

The land on which the grass grows is said to be grassland. Zebra, lions and giraffes are suited well to stay on the grassland. Thus, all the given organisms are the inhabitants of grasslands.
Question 8
1 / -0

Why are trees in the mountains regions normally cone shaped and have sloping branches?

A
To retain water

B
To slide off snow and rain water

C
To reduce transpiration

D
To enhance water conduction

Solution

Mountain regions have a lower temperature and have extensive rain fall and snow fall. So, the trees growing in the mountain regions are adapted to grow there by having cone shaped and sloping branches so that the rain water or snow does not reside over there and gets removed itself.
Question 9
1 / -0

What kind of adaptation is found in mountain goat for running up the mountain's rocky slopes?

A
Humps

B
Strong hooves

C
Thick skin

D
Padded feet

Solution

Mountain rocky slopes are generally slippery to walk over. Animals living an the mountains have strong hooves so as to hold the ground surface well without getting slipped off.
Question 10
1 / -0

Which of the following features of deer does not help to escape predators?

A
Long ears

B
Strong teeth

C
Fast running ability

D
Side eyes

Solution

Deer is a plant-eating animal living in the grassland. To hear even minute noise, it has long ears to protect itself from its predator, also for the same reason it has the legs well suited to run fast. It has got the side eyes to see that its predator does not catch it. Strong teeth cannot help the deer to escape predators.
Question 11
1 / -0

What kind of roots are observed in hydrilla?

A
Poorly developed roots

B
Deep roots

C
Fibrous roots

D
Well developed root system

Solution

Hydrilla is an aquatic plant, i.e. it lives in water. It has poorly developed roots because its body is in direct contact with water which acts as absorptive surface to absorb water and minerals.
Question 12
1 / -0

What is the characteristic climate of the mountain regions?

A
Warm and moist

B
Cold and windy

C
Hot and dry

D
Salty

Solution

Generally, the temperature in the mountain regions is lower. Also, the cold winds keep blowing over there, so the climate of the mountain regions is cold and windy.

A
To absorb nutrients from soil

B
To absorb water from soil

C
To hold the plant in place

D
To transport mineral and water

Solution
