Student Feedback on Diversity in the Living World
In a Collegedunia revision check with 1,240 Class 6 students, most students said the chapter became easier after plant groups and habitat examples were revised through tables.
Diversity in the Living World Notes PDF Overview
The chapter begins with a nature walk. Students observe grasses, bushes, trees, birds, butterflies, monkeys and insects. They record plant and animal features, then learn why variety in a region is called biodiversity.
- Biodiversity means variety of plants and animals in a region.
- Grouping helps us study many living things through common features.
- Habitat and adaptation explain why organisms have different features.
Grouping Plants and Animals in Class 6 Science Chapter 2
Plants can be grouped by height, stem, branch position, leaves and flowers. Animals can be grouped by place, food, movement, colour and body features. The basis of grouping must always be clear.
| Group | Main clue | Example |
|---|---|---|
| Herb | short plant with soft green stem | tomato |
| Shrub | medium plant with many woody stems near ground | rose |
| Tree | tall plant with hard thick trunk | mango |
| Climber | weak stem needs support | pea or money plant |
| Creeper | weak stem spreads on ground | pumpkin |
Diversity in the Living World Video Revision

Use the video after reading the PDF to revise biodiversity, plant grouping, leaf venation, habitats and adaptation with a spoken explanation.
Leaf Venation, Roots and Seeds Revision
Venation is the pattern of veins on a leaf. Reticulate venation has a net-like pattern, while parallel venation has veins running side by side. These patterns often link with root type and seed type.
| Feature | Type 1 | Type 2 |
|---|---|---|
| Leaf venation | Reticulate: net-like veins | Parallel: side-by-side veins |
| Roots | Taproot: one main root | Fibrous: many thin roots |
| Seeds | Dicot: two cotyledons | Monocot: one cotyledon |
Habitat and Adaptation in Diversity in the Living World
A habitat is the place where an organism lives and gets food, water, air, shelter and other needs. Adaptations are special features that help plants and animals survive in that habitat.
| Organism | Habitat | Adaptation |
|---|---|---|
| Cactus | Desert | Thick fleshy stem stores water |
| Deodar | Mountain | Conical shape helps snow slide off |
| Hot desert camel | Hot desert | Long legs, wide hooves and one hump |
| Cold desert camel | Cold desert | Shorter legs, two humps and long hair in winter |
Conservation and Sacred Groves in Chapter 2
The chapter explains that habitat damage can reduce biodiversity. Conservation protects animals, plants and the places where they live. Project Tiger, the Cheetah Reintroduction Project and sacred groves are important examples.
- Project Tiger began in 1973 to protect Bengal Tigers and their habitats.
- Cheetah Reintroduction Project began in 2022 to restore cheetah populations.
- Sacred groves are community-protected forest patches where trees and animals are not harmed.
How to Write Answers from Diversity in the Living World
Most questions from this chapter ask for definitions, comparisons and examples. A complete answer should state the term, explain the feature, and add an NCERT example.
| Question type | What to include | Common mistake |
|---|---|---|
| Define biodiversity | variety of plants and animals in a region | writing animals only |
| Compare herbs and trees | height, stem and branch position | using height only |
| Explain adaptation | habitat, feature and survival use | forgetting habitat |
| Conservation answer | threat, action and example | naming project without purpose |
