Diversity in the Living World Class 6 Notes: CBSE Science Chapter 2

Important Topics the Chapter Covers

1. Introduction to Diversity

• Meaning of Diversity: Diversity refers to the variety of living things found on Earth, including plants, animals, and microorganisms.

• Why Diversity is Important: It helps to balance ecosystems. Each living thing has its role, like how plants provide oxygen and food.

• Different Types of Living Beings: There are many kinds of living beings, like trees, fish, birds, and insects, all with unique characteristics.

• How Diversity Helps Nature: The variety in living beings allows nature to function smoothly, like bees helping plants grow by pollination.

• Learning from Nature: Understanding diversity helps us appreciate the world around us and teaches us to take care of all living creatures.

2. Classification of Living Beings

• What is Classification?: Classification is the way we group living beings based on their similarities, like grouping animals that live in water.

• Why Classification is Needed: It makes it easier to study and understand the millions of different species on Earth.

• Groups in Classification: Living beings are grouped into animals, plants, and microorganisms. Animals are divided into further categories like mammals, birds, and reptiles.

• How Classification Helps Scientists: It helps scientists organise and study living things in a systematic way.

• Real-Life Examples: For example, cats and lions are both mammals, so they are placed in the same group.

3. Different Habitats of Living Beings

• What is a Habitat?: A habitat is the natural environment where a living being survives, like forests for tigers and oceans for fish.

• Types of Habitats: Common habitats include forests, deserts, mountains, and oceans.

• Adaptation in Habitats: Animals and plants adapt to their habitats. For example, camels have adapted to live in deserts with less water.

• Why Habitats are Important: They provide everything needed for survival—food, shelter, and the right climate.

• Human Impact on Habitats: Humans sometimes destroy habitats, which can harm the animals and plants living there.

4. How Animals are Different from Plants

• Basic Differences: Plants make their food through photosynthesis using sunlight, while animals need to eat food to survive.

• Mobility: Animals can move around to find food, but most plants stay in one place.

• Reproduction: Plants reproduce by seeds, while animals reproduce in different ways, such as laying eggs or giving birth.

• Respiration: Plants take in carbon dioxide and release oxygen, while animals breathe in oxygen and release carbon dioxide.

• Use of Senses: Animals have different senses like sight, hearing, and smell, which plants do not have.

5. Importance of Biodiversity

• What is Biodiversity?: Biodiversity means the variety of living things in a particular place, like forests or oceans.

• Biodiversity Maintains Balance: It keeps the ecosystem healthy. For example, predators control prey populations.

• How Biodiversity Helps Humans: It provides us with food, medicine, and clean air.

• Threats to Biodiversity: Activities like deforestation and pollution can harm biodiversity.

• Conserving Biodiversity: Protecting different species and habitats is important to maintain balance in nature.

Summary of the Chapter

• There are many kinds of plants and animals around us, making up biodiversity.

• We can group plants and animals by looking at their similarities and differences.

• Plants can be compared based on their roots, stems, leaves, flowers, and other features.

• Grouping things by their common characteristics is called classification.

• Plants are classified into herbs, shrubs, and trees depending on their height, stem type, and branching patterns.

• They can also be divided into dicots and monocots based on how many seed leaves (cotyledons) they have.

• Monocots usually have parallel veins in their leaves and fibrous roots, while dicots have a network of veins and taproots.

• Animals move in different ways, and this can help in classifying them.

• The variety of living things in different areas depends on the local environment.

• Plants and animals have special features, called adaptations, that help them survive in their environment.

• The place where plants and animals live is known as their habitat.

• We can divide living things into land-based (terrestrial) and water-based (aquatic) groups, depending on where they live.

• When habitats are damaged, plants and animals lose their homes, food, and resources, which reduces biodiversity.

• It is important to protect biodiversity so that plants and animals can continue to live and grow on our planet.

Terminologies Used in the Chapter

• Diversity: The variety of different plants and animals around us.

• Grouping: The process of putting similar plants or animals together based on their common features.

• Herbs: Small plants with soft, green stems.

• Shrubs: Medium-sized plants with hard, brown stems that branch close to the ground.

• Trees: Tall plants with thick, hard stems and branches that grow higher up.

• Dicotyledons (Dicots): Plants that have seeds with two parts, also known as dicot plants.

• Monocotyledons (Monocots): Plants that have seeds with only one part.

• Venation: The pattern of veins in the leaves of plants.

• Parallel Venation: A pattern where the veins in a leaf run parallel to each other.

• Reticulate Venation: A pattern where veins form a net-like structure in the leaf.

• Fibrous Roots: A type of root system where many thin roots spread out from the base of the plant.

• Taproot: A root system where one large root grows downwards, with smaller roots growing out of it.

• Biodiversity: The variety of life in a particular area, including plants, animals, and other organisms.

• Adaptations: Special features that help plants and animals survive in their specific environment.

• Habitat: The natural home or environment of a plant or animal.

• Terrestrial: Refers to living on land.

• Aquatic: Refers to living in water.

• Sacred Groves: Areas of forest that are protected by local communities because they are considered sacred.
