NCERT Solutions for Class 8 Science - Animal - Habitat and Adaptation

Q1: Define Habitat and Adaptation.
Ans: 
Habitat: A habitat is the natural home or environment where an animal, plant, or organism lives. It's like their "Neighbourhood" or "house". Habitats provide everything an animal needs to survive, such as food, water, shelter, and suitable living conditions.

Adaptation: Adaptation is the process by which animals, plants, and organisms change or develop special features to survive and thrive in their habitats.

Ans: A habitat is a place where an animal lives. It provides everything an animal needs to survive and grow such as: 

  • Shelter: A habitat that gives animals a safe place to live and hide from predators. It provides them with protection from extreme weather conditions like rain, sun, and cold.  
  • Food: Habitats provide animals with a source of food. Different habitats have different types of food available.   For instance, forests provide nuts, fruits, and insects, while oceans provide fish and other marine creatures.  
  • Water: Water is essential for the survival of animals. Habitats like lakes, rivers, and ponds provide water for animals to drink and bathe in.  
  • Oxygen: Just like humans, animals need oxygen to breathe. Habitats such as forests and grasslands have plants that produce oxygen through a process called photosynthesis. Animals inhale this oxygen to stay alive.
  • Space: Habitats offer animals enough space to move around and find what they need. Some animals require large territories to find food or mates, while others need smaller spaces.
  • Suitable climate: Habitats provide animals with a climate that suits their needs. Some animals prefer hot climates, while others thrive in colder environments.  

Q3: Name any three breathing organs in animals.
Ans: The three breathing organs in animals are:

  • Lungs: Lungs are the breathing organs found in many animals. Lungs help animals breathe in oxygen and breathe out carbon dioxide.  
  • Gills: Gills are breathing organs found in many aquatic animals such as fish. They are located on the sides of the fish's head, behind the gill covers.  
  • Spiracles and Tracheae: Some insects, like grasshoppers, have a different type of breathing system. They have small openings called spiracles on the sides of their bodies.

  • These spiracles connect to a network of tiny tubes called tracheae, which extend throughout the insect's body.
  •  Air enters the spiracles and travels through the tracheae, delivering oxygen directly to the cells.  

Q4: Describe the different types of habitats listing their special features.
Ans: The different types of habitats are:

(i) Forest: 

  • It is a large area that is covered by trees and plants. Forest provides shelter to a large number of animals.
  • For example – lion, tiger, monkey etc.

(ii) Desert: 

  • A desert is a dry, often sandy region that receives very little rainfall. It is usually very hot during the day and very cold during the night.
  • Water is hard to find in deserts. Animals found in deserts are Camel, rattlesnakes and ground squirrels.

(iii) Polar Regions and Mountains: 

  • The polar regions – Antarctica and the Arctic and high mountains are extremely cold and covered with snow.
  • Penguins, seals and Walrus are found in Polar regions.

  • The ocean is a large, continuous body of salt water that covers two-thirds of the earth’s surface.
  • It is the world’s largest habitat.
  • It is divided into the Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean and Southern Ocean.
  • A large variety of fish are found in the ocean such as Whales, octopuses and jellyfish are a few to name.

(v) Fresh Water: 

  • Rivers, Lakes and Ponds are examples of freshwater habitats.
  • Some animals live in water for example fish and shrimp. 
  • Some animals live both on land and water they are called amphibians for example frogs and salamanders.

Q5: Describe the different body coverings of animals with examples.
Ans: The different body coverings of animals are:

(i) Scales: 

  • Fish are covered with a layer of flexible, overlapping scales.
  • The bodies of reptiles like snakes, crocodiles and lizards too are covered with scales.
  • Most reptiles have horny scales that prevent water loss from their bodies.

(ii) Shell: 

  • Animals like snails, tortoises and turtles are protected by a shell.
  • These animals withdraw their head and feet into the shell when they sense danger.

(iii) Wool or Fur: 

  • Mammals like sheep and bears have special body coverings.
  • A sheep’s body is covered with wool and a bear’s body is covered with fur. These coverings protect them from rain and cold.

Polar Bear Polar Bear (iv) Feathers: 

  • Birds are covered with feathers.
  • Feathers help them to fly. They also protect the birds from rain and cold.

Q6: Explain how animals are adapted to move in different ways.
Ans: Different types of animals have different types of organs to move like:

  1. Animals like dogs and cats move with the help of their legs.
  2. Birds fly with the help of their wings.
  3. Most snakes move with the help of scales on the underside of their body.
  4. Fish, dolphins and whales swim with the help of fins.
  5. Penguins and seals have flippers which help them to swim.
  6. Frogs hop around using their strong back legs. Their webbed feet help them to swim.

Q7: Define Moulting, Camouflage, and spiracles.
Ans:
Moulting: 

  • Moulting is a process in which animals shed or replace their outer covering, such as feathers, and skin to allow for growth and renewal.
  • It is like when you shed old clothes and wear new ones.
  • During moulting, the old covering is replaced with a new one.  
  • For example, snake shed their skin periodically and these are replaced by new ones.

Camouflage: 

  • Camouflage is a way for animals to blend in or hide in their surroundings.  
  • Camouflage allows animals to match the colours, patterns, and textures of their environment, making it difficult for others to see or notice them.
  • It helps them stay protected from predators or become better hunters.  For example, chameleon

Spiracles: 

  • Insects breathe with the help of a series of tiny holes along the side of their bodies. These holes are called spiracles.
  • Spiracles are like little entry points for air to reach the insect's respiratory system, allowing them to breathe.  
  • For example, spider and Indian moon moth.

FAQs on NCERT Solutions for Class 8 Science - Animal - Habitat and Adaptation

1. What is the definition of a habitat?
Ans. A habitat is the natural environment or home of an animal, plant, or other organism. It provides the necessary resources, such as food, water, shelter, and space, for the organism to survive and thrive.
2. How do animals adapt to their habitat?
Ans. Animals adapt to their habitat through various ways such as physical adaptations (e.g., camouflage, sharp claws, strong beak), behavioral adaptations (e.g., migration, hibernation, burrowing), and physiological adaptations (e.g., ability to tolerate extreme temperatures, producing venom).
3. What happens if an animal is not well-adapted to its habitat?
Ans. If an animal is not well-adapted to its habitat, it may struggle to find food, water, or shelter, which can lead to a decrease in its population. In extreme cases, it may not survive in that habitat and may need to migrate to a more suitable one or face the risk of extinction.
4. How do different habitats affect animal species?
Ans. Different habitats have different features and resources, which influence the types of animal species that can thrive in them. Some habitats, such as rainforests, support a wide variety of species due to their high biodiversity, while others, like deserts, may have fewer species adapted to the harsh conditions.
5. What are some examples of animal adaptations to specific habitats?
Ans. Some examples of animal adaptations to specific habitats include a polar bear's thick fur and layer of blubber for insulation in cold Arctic environments, a chameleon's ability to change color to blend with its surroundings in forests, and a kangaroo's powerful hind legs for hopping and escaping predators in open grasslands.
