The World of Living

Welcome to the chapter on The World of Living for Class 6. In this chapter, you will explore the amazing variety of living things around us, learn what makes something "living," and understand how living things interact with each other and their environment. By the end of this chapter, you will be able to identify living things, describe their features, and explain their importance in nature!

Introduction

The world is full of living thingsā€”plants, animals, and tiny organisms. Living things are different from non-living things because they grow, move, reproduce, and respond to their surroundings.

Characteristics of Living Things

  • Living things need food, water, and air.
  • They grow and change over time.
  • They can move on their own.
  • They reproduce (have babies or make seeds).
  • They respond to changes around them (like light, sound, or touch).
  • They get rid of waste from their bodies.

Types of Living Things

  • Plants: Make their own food using sunlight. Examples: trees, grass, flowers.
  • Animals: Eat plants or other animals. Examples: birds, fish, insects, mammals.
  • Microorganisms: Tiny living things we cannot see without a microscope. Examples: bacteria, fungi, algae.

How Living Things Interact

  • Plants give food and oxygen to animals.
  • Animals help plants by spreading seeds and pollinating flowers.
  • Microorganisms help break down dead plants and animals, making soil rich.

Importance of Living Things

  • Living things keep nature balanced.
  • They provide food, shelter, and oxygen.
  • They help recycle nutrients in the environment.

Fun Activity: Nature Walk

Go for a walk in a garden or park. Make a list of all the living things you seeā€”plants, animals, insects, and birds!

Summary

  • Living things grow, move, reproduce, and respond to their surroundings.
  • Plants, animals, and microorganisms are all living things.
  • Living things interact and help keep nature healthy.

Practice Questions

  1. Name three characteristics of living things.
  2. Give two examples of microorganisms.
  3. How do animals help plants?
  4. Why are living things important for nature?
  5. What do plants need to make their own food?

Challenge Yourself

  • Draw and label the parts of a plant and an animal.
  • Write a short paragraph about how living things depend on each other.

Did You Know?

  • Some microorganisms can live in very hot or cold places!
  • The largest living thing on Earth is a fungus in Oregon, USA!

Glossary

  • Living thing: Something that grows, moves, and reproduces.
  • Microorganism: A tiny living thing seen only with a microscope.
  • Reproduce: To have babies or make seeds.
  • Pollinate: To help plants make seeds by moving pollen.

Answers to Practice Questions

  1. Grow, move, reproduce (any three: grow, move, reproduce, respond, need food, remove waste).
  2. Bacteria, fungi (any two: bacteria, fungi, algae).
  3. By spreading seeds and pollinating flowers.
  4. They keep nature balanced and provide food, oxygen, and shelter.
  5. Sunlight, water, air, and nutrients from soil.
