NCERT Class 6 Science Chapter 2
Diversity in the Living World
This chapter helps Class 6 CBSE students appreciate the vast variety of living organisms on Earth, covering the classification of plants and animals based on their characteristics. Students learn about key concepts like habitat, adaptation, and biodiversity, understanding how different species are suited to their environments. The chapter also explores the importance of naming and classifying organisms for scientific study.

Frequently Asked Questions
What is biodiversity in Class 6 Science?▾
Biodiversity refers to the wide variety of living organisms found on Earth, including plants, animals, and microorganisms. Class 6 Chapter 2 explains how this diversity exists across different habitats and ecosystems.
How are living organisms classified in Class 6?▾
Living organisms in Class 6 are classified based on their characteristics such as body structure, mode of nutrition, habitat, and reproduction. They are broadly grouped into plants, animals, fungi, and microorganisms.
What is adaptation in Class 6 Science Chapter 2?▾
Adaptation refers to the special features that help an organism survive in its environment. For example, a cactus has thick stems to store water for survival in deserts, and a fish has gills to breathe underwater.
Why is classification of living organisms important in Class 6?▾
Classification helps scientists organize and study the millions of species on Earth. It makes communication easier, helps in identifying new species, and helps understand evolutionary relationships between organisms.
What is the difference between habitat and adaptation?▾
A habitat is the place where an organism lives (like a forest, pond, or desert), while adaptation is the feature or behavior that allows the organism to survive in that habitat (like webbed feet in ducks for swimming).
