The Living Organisms and their Surroundings Class 6th Question Answers
Overview of Chapter
- ORGANISMS AND THE SURROUNDINGS WHERE THEY LIVE.
- HABITAT AND ADAPTATION.
- A JOURNEY THROUGH DIFFERENT HABITATS.
- Some Terrestrial Habitats.
- Some Aquatic Habitats.
- CHARACTERISTICS OF THE LIVING BEINGS.
ORGANISMS AND THE SURROUNDINGS WHERE THEY LIVE: All the places on the earth whether they are cold, hot dry, moist or humid have organisms of different kinds. The kinds of plants and animals found in one region are different from another region.
HABITAT AND ADAPTATION: The place where an organism lives, is called the habitat. It is a part of the total environment of the region. It provides the living organism with food, shelter and favourable climatic conditions to survive, breed and flourish.
The presence of specific features or certain habits, which enable a plant or an animal to live in its surroundings, is called adaptation. Different animals are adapted to their surroundings in different ways.
A JOURNEY THROUGH DIFFERENT HABITATS
- Some Terrestrial Habitats.
- Deserts: These habitats include a vast area of land with sand and little or no vegetation. They have very little rainfall and are hot and dry.
- Mountain Region: These areas are generally hilly cold and windy. They receive snowfall during winter. There are some mountains which always remain covered with snow.
- Forests or Grasslands: A large area of land covered mainly with trees and plants is called a forest while a large area of grass-covered land used for grazing is called grassland.
- Some Aquatic Habitats.
- Oceans: A very large area of the sea is called an ocean. The ocean is a saline water aquatic habitat having water all around.
- Ponds, Lakes and Rivers: Ponds, Lakes and Rivers are freshwater aquatic habitats. The plants which grow in water are called aquatic plants. There are three types of aquatic plants: free-floating, partially submerged and completely submerged plants.
CHARACTERISTICS OF THE LIVING BEINGS: All living things have some common characteristics which make them different from non-living things. The characteristics of living things are given below:
- Living things need food, air, and water.
- They can grow.
- They can respire.
- They can respond to stimuli because they are sensitive.
- They can move from one place to another.
- They can excrete waste materials from their body.
- They can reproduce and give birth to their young ones.
- They have a fixed lifespan.
The Living Organisms and their Surroundings Class 6th Questions
1. What is a habitat?
Ans. The surroundings or place where an organism (plant or animal) live is called a habitat. The organisms depend on their habitat for food, air, water, shelter, and other needs.
2. Why is the adaptation necessary? (JKBOSE)
Ans. The special physical features which enable a plant or an animal to live in its surroundings is called adaptation. Adaptation is necessary for the survival of an organism.
3. How are cacti adapted to survive in a desert?
Ans. Cactus are adapted to survive in the desert with help of the following features:
1. The leaves are either absent or modified into the spine to prevent loss of water due to respiration.
2. The stem of a cactus plant is modified to perform the function of photosynthesis due to the presence of chlorophyll in it.
3. The stem of cactus plant has a thick waxy layer on it to prevent loss of water.
4. The roots of cactus plants are well-developed and go deep into the soil for absorbing water.
4. Why is the body of water plants covered with mucilage? (JKBOSE)
Ans. The body of water plants is covered with mucilage because it protects them from decaying and also helps the plant to float on the surface of the water.
- Fill up the blanks

(c) The habitats of plants and animals that live in water are called _______ habitats.
(d) Soil, water and air are the _______ factors of a habitat.
(e) Changes in our surroundings that make us respond to them are called _______.
(f) Water lily plant shows _______ adaptation. (JKBOSE)
(a) The presence of specific features, which enable a plant or an animal to live in a particular habitat, is called adaptation.
(b) The habitats of the plants and animals that live on land are called terrestrial habitats.
(c) The habitats of plants and animals that live in water are called aquatic habitats.
(d) Soil, water and air are the abiotic factors of a habitat.
(e) Changes in our surroundings that make us respond to them are called stimuli.
(f) Water lily plant shows aquatic adaptation. (JKBOSE)
- Which of the things in the following list are non-living?
Plough, Mushroom, Sewing machine, Radio, Boat, Water hyacinth, Earthworm
Ans. Non-living things do need food, air, and water. In the given list plough, sewing machine, radio, and boat are non-living.
- Give an example of a non-living thing, which shows any two characteristics of living things.
Ans. The most common example of a non-living thing which shows characteristics of a living thing is clouds. It grows in size with time, and also moves from one place to another.
- Which of the non-living things listed below, were once part of a living thing?
Butter, Leather, Soil, Wool, Electric bulb, Cooking oil, Salt, Apple, Rubber
Ans. Butter, Leather, Wool, Cooking oil, Apples and Rubber are non-living things which were once part of a living thing.
- List the common characteristics of living things. (JKBOSE)
Ans. The following are common characteristics of living things:
- Living Things
- Can grow.
- Need food, air, and water to survive.
- Can move by themselves.
- Respond to stimuli. (They are sensitive)
- Have a definite life span.
- Explain 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 grassland habitats.)
Ans. Since there are few trees or places for animals to hide in grassland habitats. So, to prevent themselves from predators animals living in grasslands need more speed. For example, a tiger eats deer so the deer has to run faster than a tiger to protect itself from the tiger.
- How do plants differ from animals? Give important differences.
|1. Plants are fixed in one place and cannot move||1. Animals can leave their place and move from one place to another.|
|2. Plants have chlorophyll in them||2. Animals do not possess chlorophyll.|
|3. Plants grow till their death.||3. Animals grow up to a certain age in their life.|
|4. Plants prepare their food through the process of photosynthesis.||4. Animals cannot prepare their food; they obtain food from plants or other animals.|
|5. Plants produce oxygen during the process of photosynthesis.||5. Animals produce carbon dioxide during the process of respiration|
