Worksheet 9: Class 6 Science - The Living Organisms and Their Surroundings

Welcome! This worksheet will help you understand the relationship between living organisms and their environment. We will explore what makes something living, where organisms live, and how they adapt to their surroundings. Let's learn about the diverse habitats on our planet!

Habitats and Adaptation

A **habitat** is the home or dwelling place of an organism. It provides an organism with everything it needs to survive, such as food, water, and shelter. Different organisms live in different habitats, like deserts, mountains, oceans, and forests. The living things that are found in a habitat are called its **biotic components**, and the non-living things are called **abiotic components**.

Examples of biotic components include plants, animals, and microorganisms. Abiotic components include air, water, soil, light, and temperature. All living organisms depend on both biotic and abiotic factors for their survival.

The ability of an organism to adjust to its surroundings is called **adaptation**. For example, a camel has adapted to live in the desert. It has long legs to keep its body away from the hot sand and can survive for many days without water. Similarly, a fish has gills to breathe in water, which is an adaptation to its aquatic habitat.

Practice Questions

1. Fill in the blank: The home or dwelling place of an organism is called its _____.

Habitat

2. True or False: All living organisms can survive in the same habitat.

False. Different organisms have different needs and are adapted to live in different habitats.

3. Match the item to its category:

(a) A tree (i) Abiotic Component

(b) Water (ii) Biotic Component

(c) A dog (iii) Abiotic Component

(d) Soil (iv) Biotic Component

a - ii, b - i, c - iv, d - iii

4. What is adaptation? Give one example of a plant that has adapted to a desert environment.

**Adaptation** is the process by which an organism develops features that help it survive in its habitat. A cactus is a plant that has adapted to the desert; its stem stores water and its leaves are reduced to spines to prevent water loss.

5. Fill in the blank: The two main components of a habitat are _____ and _____ components.

Biotic and Abiotic

6. Why can a fish not survive on land?

A fish cannot survive on land because it has gills to breathe oxygen dissolved in water, not air. It is adapted to an aquatic habitat.

7. Name three features of living organisms.

Living organisms can grow, move, breathe, and reproduce.

8. What is the difference between a mountain habitat and an aquatic habitat?

A **mountain habitat** is characterized by cold weather and rocky soil. An **aquatic habitat** is in a body of water, such as a pond, lake, or ocean.
