Important Questions Class 6 Science Chapter 9 – The Living Organisms Characteristics and Habitats
Science is described as the study of natural events by observation, identification, description, experimental inquiry, and theoretical justification. Science answers daily life’s problems and aids in our quest to unravel the cosmos’ greatest mysteries.
The Living Organisms’ Characteristics and Habitats is the Ninth Chapter in the Class 6 Science syllabus. This chapter deals with the organisms and the surroundings where they live; their habitats and adaptations; and the characteristics of organisms. An environment where a specific species generally resides is referred to as a habitat. Habitat is important because organisms, including animals, birds, and plants, rely on it for their air, food, water, shelter, and other survival necessities. Adapting animals and plants to a specific habitat gives them the ability to live there successfully. Organisms need to adapt to the circumstances and environment in which they survive.

(a) Excretion takes place in plants.
(b) Excretion takes place both in plants and animals.
(c) Excretion is the process of only getting rid of excess water.
(d) Secretion is one method of Excretion.
Answer 5: (c) Excretion is only the process of getting rid of excess water.
Explanation: Waste products like water, carbon dioxide, and nitrogenous substances are expelled through excretion. Waste products are created throughout the numerous biological processes within an organism’s body and are expelled from the body through urine, sweat, and exhaled air.
Question 6. Which of the things in the following items is non-living?
Plough, Sewing Machine, Mushroom, Radio, Boat, Water Hyacinth, Earthworm
Answer 6: The boat, sewing machine, radio, and plough are the only non-living items on the list. On the other hand, earthworms, mushrooms, and water hyacinths are all living things.

(a) (i), (ii) and (iv) only
(b) (i) and (ii) only
(c) (ii) and (iv) only
(d) (i), (ii), (iii) and (iv)
Answer 7: (d) (i), (ii), (iii) and (iv)
Explanation: All living things require respiration to survive. The body finally gets energy from the food it consumes through respiration. Through reproduction, living things create more of their kind. Living things adjust to their environment as it evolves. Only those creatures and plants that can adapt to changes survive, wiping out all others. During the processes of life, a living organism’s body creates waste. These wastes are eliminated, and the live organism’s method of doing so is known as Excretion.
Question 8. Name the types of components of habitat.
Answer 8: Components of habitat are:
(i) Biotic components
(ii) Abiotic components
Choose the set that represents only the biotic components of a habitat.
(a) Tiger, Deer, Grass, Soil
(b) Rocks, Soil, Plants, Air
(c) Sand, Turtle, Crab, Rocks
(d) Aquatic plant, Fish, Frog, Insect
Answer 9: (d) Aquatic plant, Fish, Frog, Insect
Explanation: Aquatic plants, fish, frogs, and insects are living components or biotic components of the environment. Soil, rocks, air and sand are nonliving or abiotic components. So only set (d) has all the living or biotic components.
Question 10. List the common characteristics of living things.
Answer 10: Few common characteristics of living things are:
- They can grow and develop.
- They can reproduce.
- They obtain and use energy.

Aquatic habitats – Pond, Ocean
Question 24. Elaborate on why speed is important for survival in the grasslands for animals that live there (Hint: There are few trees or places for animals to hide in grasslands habitat).
Answer 24: Grasses predominate in grasslands. There are not many trees. These areas are frequently home to predators like lions, tigers, and others that prey on other species. These predators find their prey in the grass quite quickly. Animals, therefore, adjust by becoming faster to defend themselves from these predators. The faster animal protects itself and improves its chances of life by assisting the smaller, more vulnerable creatures in escaping their predator.
Question 25. Choose the odd one out from below with respect to reproduction.
(a) Eggs of hen
(b) Seeds of plants
(c) Buds of potato
(d) Roots of the mango tree
Answer 25: Mango tree roots are vegetative portions of the tree and do not participate in reproduction. Plant seeds and chicken eggs are examples of reproductive goods. Potato plants can reproduce vegetatively by producing new plants from their buds.
Question 26. How have camels adapted to live in the desert?
Answer 26: A camel is adapted to desert conditions. The following adaptations are found in camel :
- The animal has a fat-filled hump on its back. When the camel has nothing to eat, it uses this food.
- It has long legs to keep its body out of the sand’s heat.
- The hooves of the camels are covered by a large sole that helps them move on the hot slippery sand.
- Water is equally dispersed throughout the animal’s body, not only in one pocket or organ.
- It excretes extremely little water through dry dung from its body.
Question 27. How have cacti adapted to survive in a desert?
Answer 27: The cacti adapts itself in the desert in following ways:
- It has a modified flat, green stem that conserves water and uses photosynthesis to prepare food.
- The stem has a thick, waxy layer covering it, which aids in water retention.
- To stop water loss through transpiration, there are leaves present that have spines.
- Long roots delve down into the ground to absorb water.
Question 28. What do you mean by acclimatisation?
Answer 28: Acclimatisation is the process through which an organism undergoes changes over a short period of time that enable it to adapt to its environment.
Question 29. Name the place of living of the following plants:
- Cactus: Desert
- Hydrilla: Pond.
Question 30. Write the differences between respiration and breathing.
Respiration: Respiration is the method through which living creatures use oxygen to liberate the energy contained in the food they consume.
Breathing: It is the process of inhaling and exhaling the air in and out of the lungs. When we inhale while breathing, oxygen-rich air travels from the exterior of our bodies to the inside. When we exhale, carbon dioxide-rich air leaves our bodies and travels outside.
Question 31: Describe the adaptation of plants to living in water.
Answer 31 : The adaptation of plants that takes place in aquatic habitats is as follows:
- Stems extend above the surface of the water.
- The roots are reduced in size, which holds the plant.
- Flowers and leaves float on the surface of the water.

Q.1 What is the main function of the roots in aquatic plants?
(a) Hold the plant in place
(b) Absorb nutrition
(c) Prepare food
(d) Store food
(a) Hold the plant in place
The main function of roots in aquatic plants is to hold the plant firmly at its place. They are also reduced in size. This is different from the roots of terrestrial (land) plants, where the main function of the roots is to absorb nutrients.
Q.2 Which of the following has webbed feet?
Webbed feet help ducks to swim in water.
Q.3 Which of the following structures is used by dolphins for breathing?
Dolphins do not breathe through gills like other aquatic animals. Instead, they breathe through blowholes which are present on the upper parts of their heads. They come to the surface of the water to breathe in the air and can stay in water for a long time without breathing.
Q.4 Humans and whales are both mammals that breathe air into their lungs. Then why can’t humans live underwater as whales do?
Whales have a special respiratory organ called a blowhole, located right on top of their heads. While swimming or resting under the water, a blowhole allows them to take breaths by exposing only the top of their heads to the air. A whale inspires more oxygen in a single breath than a human. For this reason, they are able to hold their breath and stay underwater for a longer period of time than human beings.
Q.5 Write and explain the adaptation in fishes due to which they are able to
a. move faster through water
b. move forward, turn, keep an upright position, or stop.
a. Streamlined body: The body of fish is long and pointed at both ends. The streamlined bodies allow most fishes to move faster in water with less resistance.
b. Fins and tail: The flat fins and tails of fishes help them to change directions underwater. For instance, the back fin helps the fish swim in a straight path while the tail fin helps it to move forward swiftly. It also helps in balancing the body in water.
