Learning Objectives
Students will:
✔ Understand the relationship between organisms and their surroundings.
✔ Explain why different organisms live in different habitats.
✔ Identify adaptations that help organisms survive.
✔ Appreciate the importance of biodiversity and environmental conservation.
Previous Knowledge (पूर्व ज्ञान)
Ask students:
- Have you seen a fish living on land?
- Can a camel live in the sea?
- Why do birds build nests?

What are Living Organisms?
English
Living organisms are things that have life.
They:
- Grow
- Breathe

हिन्दी
जीवधारी वे होते हैं जिनमें जीवन होता है।
इनकी विशेषताएँ हैं—
- वृद्धि
- श्वसन
- भोजन की आवश्यकता
- प्रजनन
- उत्सर्जन
- उद्दीपन के प्रति प्रतिक्रिया
- गति
Habitat (आवास)
Definition
English
The place where an organism lives is called its habitat.
Hindi
वह स्थान जहाँ कोई जीव रहता है उसे उसका आवास (Habitat) कहते हैं।
Components of Habitat
Biotic Components (जैविक घटक)
Living things
Examples:
- Plants
- Animals
- Bacteria
- Fungi
Abiotic Components (अजैविक घटक)
Non-living things
Examples:
- Air
- Water
- Soil
- Sunlight
- Temperature
Types of Habitats
1. Terrestrial Habitat (स्थलीय आवास)
Organisms living on land.
Examples:
- Lion
- Elephant
- Camel
- Tiger
- Human
Types:
- Forest
- Desert
- Grassland
- Mountains
- Polar Region
Adaptations in Different Terrestrial Habitats
Desert (मरुस्थल)
Camel:
- Hump stores fat.
- Long legs.
- Broad feet.
- Long eyelashes.
- Can survive with little water.
Cactus:
- Thick stem stores water.
- Leaves modified into spines.
- Waxy coating reduces water loss.
Mountain Region (पर्वतीय क्षेत्र)
Animals:
- Thick fur
- Strong legs
- Sharp claws
Plants:
- Cone-shaped trees
- Needle-like leaves
Polar Region (ध्रुवीय क्षेत्र)
Polar Bear:
- Thick fur
- Thick layer of fat (blubber)
- White colour for camouflage
Penguin:
- Streamlined body
- Thick feathers
- Fat layer for insulation
Aquatic Habitat (जलीय आवास)
Organisms living in water.
Types
- Freshwater
- Marine (Sea)
Examples
- Fish
- Whale
- Dolphin
- Lotus
- Water Lily
Adaptations in Aquatic Animals
Fish
- Gills for breathing
- Fins for swimming
- Streamlined body
- Scales
Whale
- Blowhole
- Streamlined body
- Thick fat layer
Aquatic Plants
Lotus
- Broad floating leaves
- Long hollow stem
Hydrilla
- Thin ribbon-like leaves
- Flexible stem
Adaptation (अनुकूलन)
English
Adaptation is a special feature that helps an organism survive in its habitat.
हिन्दी
जीवों में ऐसी विशेषताएँ जो उन्हें अपने वातावरण में जीवित रहने में सहायता करती हैं, अनुकूलन (Adaptation) कहलाती हैं।
