Extra 30 short questions and answers from the chapter:9 "The Living Organisms – Characteristics and Habitats" for Class 6 Science (CBSE):-
What are the main characteristics of living organisms?
Answer:
Living organisms show characteristics such as growth, movement, respiration, reproduction, excretion, and response to stimuli.
Why do living organisms need food?
Answer:
Food provides energy for growth, repair, movement, and other life processes.
What is respiration?
Answer:
Respiration is the process in which living organisms break down food to release energy.
How do plants excrete waste materials?
Answer:
Plants excrete waste through shedding leaves, transpiration, and releasing oxygen during photosynthesis.
What is the importance of movement in animals?
Answer:
Movement helps animals search for food, escape predators, find shelter, and reproduce.
How do plants show movement?
Answer:
Plants move in response to light (phototropism), gravity (gravitropism), and water (hydrotropism).
What is reproduction?
Answer:
Reproduction is the process by which living organisms produce their own kind.
What is excretion?
Answer:
Excretion is the process of removing waste materials from the body of living organisms.
How do living organisms respond to stimuli?
Answer:
Living organisms respond to stimuli such as light, heat, sound, touch, and chemicals by showing movements or changes in
behaviour
.
Why do living organisms grow?
Answer:
Growth is a fundamental characteristic of living organisms, where they increase in size, repair damaged parts, and develop new structures.
What is a habitat?
Answer:
A habitat is the natural environment where an organism lives, grows, and reproduces.
What are the two main types of habitats?
Answer:
The two main types of habitats are terrestrial (land) and aquatic (water).
Give two examples of terrestrial habitats.
Answer:
Forests and deserts are examples of terrestrial habitats.
Give two examples of aquatic habitats.
Answer:
Oceans and rivers are examples of aquatic habitats.
What is adaptation?
Answer:
Adaptation is the special characteristics that help organisms survive in their habitat.
How are desert plants adapted to survive in dry conditions?
Answer:
Desert plants have spines instead of leaves, thick stems to store water, and deep roots to absorb water.
How are fish adapted to live in water?
Answer:
Fish have gills to breathe, fins for movement, and streamlined bodies to reduce water resistance.
Why do polar bears have thick fur and fat?
Answer:
Thick fur and fat help them stay warm in cold Arctic conditions.
Why do camels have long legs and padded feet?
Answer:
Camels have long legs to keep their bodies away from hot sand and padded feet to walk on soft desert sand.
How do amphibians survive on land and in water?
Answer:
Amphibians like frogs have lungs to breathe on land and moist skin to absorb oxygen in water.
What are aquatic plants? Give two examples.
Answer:
Aquatic plants grow in water. Examples: Lotus, Water hyacinth.
What is the difference between terrestrial and aquatic animals?
Answer:
Terrestrial animals live on land (e.g., Lion), while aquatic animals live in water (e.g., Fish).
How do birds adapt to flying?
Answer:
Birds have hollow bones, feathers, strong muscles, and streamlined bodies to help them fly.
Why do deciduous trees shed their leaves in winter?
Answer:
Deciduous trees shed leaves to reduce water loss during winter.
What is camouflage? Give an example.
Answer:
Camouflage is the ability of an organism to blend with its surroundings. Example: Chameleons change
colour
to avoid predators.
Why do animals migrate?
Answer:
Animals migrate to escape extreme weather, find food, or reproduce in
favourable
conditions.
Why do whales come to the surface of the water?
Answer:
Whales have lungs, so they come to the surface to breathe air.
What is hibernation? Give an example.
Answer:
Hibernation is a long sleep during winter to conserve energy. Example: Bears hibernate in winter.
What is the function of gills in fish?
Answer:
Gills help fish extract oxygen from water for breathing.
What are nocturnal animals? Give two examples.
Answer:
Nocturnal animals are active at night. Examples: Owl, Bat.
