Exercise Questions
1. What is a habitat?
Solution:
The place where organisms live is called the habitat. Habitat means a dwelling place (a home). The habitat provides food, water, air, shelter and other needs to organisms.
2. How is a cactus adapted to survive in a desert?
Solution:
Adaptations of a cactus are as follows:
-
The leaf is replaced by the spine to reduce transpiration
-
Stems carry out photosynthesis
-
A thick waxy layer surrounds the leaf to retain water
-
The roots of a cactus are deeply rooted inside the soil to absorb water

NCERT Class 6 Science Chapter 9 The Living Organisms and Their Surroundings Topic-Wise Discussion
We have discussed the topics taught in chapter 9 of NCERT class 6 science in the sections below:
9.1 Living Things and Their Environments
Our Earth is a vast expanse with different regions where various kinds of living beings establish their permanent homes. The inhabitants of these areas are referred to as organisms. It's fascinating to discover that even the openings of volcanoes serve as homes for tiny living creatures. Similarly, the places where humans reside become habitats for specific organisms. Simply put, the surroundings in which animals live are known as habitats. Organisms rely on their habitats for necessities like food, air, water, shelter, and more.
NCERT Solutions For Class 6 Science Chapter 16
9.2 Habitats and Adaptation
Now that we understand habitats, let's explore adaptation. Plants and animals undergo changes in their habits and characteristics based on their environment, enabling them to survive in that specific habitat. This phenomenon is called adaptation. To observe this yourself, take a notebook and pencil on a family trip. You'll observe that depending on the region and nature, the plants, animals, and even the physical condition of humans vary.
To simplify, consider the plants and animals in bodies of water like seas, oceans, rivers, and lakes. All of them rely on dissolved air in the water. In deserts, where water is scarce, plants and animals adapt to conditions that allow them to breathe air from their surroundings.
NCERT Solutions For Class 6 Science Chapter 7
9.3 A Journey Through Different Habitats
Deserts – Because of a lack of water, leaves on desert plants shrink into spines, helping to reduce water loss through transpiration. Rats and snakes live in burrows to escape the intense heat, emerging only after the sunsets.
Mountains – Trees have a cone shape, and most leaves feature thorns to minimise space for rainwater and snow accumulation. Many animals have thick fur to shield themselves from the extreme cold.
Grasslands – Plants and trees in these areas are vibrant green during the rainy season but turn pale brown in the dry season. Animals adapt to changing seasons, making these regions highly productive landscapes.
Aquatic/Marine Habitats – Organisms residing in oceans and seas have streamlined gills and bodies, enabling them to peacefully thrive in salty water.
Freshwater – Organisms that can't survive in salty water choose freshwater habitats, such as ponds, lakes, and rivers.

9.4 Living Things Around Us
The Earth has both living and nonliving things. Living things breathe and grow, while non-living things cannot do so.
All living things need food to survive, and the type of food depends on their living conditions and environment.
Living things grow because they are made of cells and tissues. These continue to grow, making the organism mature and part of the reproduction cycle. Respiration is essential for all living organisms to get energy from the food consumed. The way they breathe may vary depending on adaptation.
Living beings can change themselves based on the situation and respond to stimuli. Stimuli cause living organisms to adjust to the environment. Every living thing is part of the reproductive system, helping in growth and reproducing to increase the population based on the surroundings.
As living organisms consume food, some parts become waste, which they get rid of through excretion. In plants, this process is called secretion.
Not all living things can move. Examples include plants, trees, and bushes. Only animals can move to find food and perform other actions. Trees, for instance, stay rooted in soil and obtain their food from nature.
In simpler terms for 6th standard education, life is a process where living organisms grow, feed, move, eat, feel, respire, excrete, and reproduce, bringing the joy of existence.
