Class 6 Science · Chapter 2
Short answer: Chapter 2 "Diversity in the Living World" Class 6 Science Curiosity book bataata hai ki living aur non-living cheezon me farak kaise karein, characteristics of living organisms kya hote hain, aur duniya bhar ke jeev-jantu apne habitat ke hisaab se kaise adapt karte hain.
Class 6 Science Curiosity book ka Chapter 2 — "Diversity in the Living World" — Chapter 1 "The Wonderful World of Science" ke baad aata hai, aur wahan se seedhe connect hota hai: Chapter 1 me humne dekha tha ki science observation aur curiosity se shuru hoti hai, aur ab Chapter 2 me hum wahi curiosity apply karte hain apne aas-paas ki living duniya par.
Ye chapter students ko sikhata hai ki Earth par kitni tarah ke jeev-jantu paaye jaate hain — chhoti bacteria se lekar bade whale tak, desert ke cactus se lekar deep-sea coral tak. Is diversity ko samajhne ke liye pehle ye jaanna zaroori hai ki 'living' hota kya hai, aur non-living se ye kaise alag hai. Agar 'NCERT Class 6 Science Curiosity chapter wise notes' dhoondh rahe ho, toh ye chapter foundation set karta hai jo aage 'Living Creatures: Exploring their Characteristics' jaise chapters me deeply explore hota hai.
Is content spec me hum poora chapter cover karenge — characteristics of living organisms, habitat-based adaptations, classification ke basic clues, aur exam-oriented Q&A, taaki 'Diversity in the Living World class 6 notes PDF' ki tarah ek complete self-study resource mil sake.
Chapter 2 Summary — 5 Minute Revision
Diversity in the Living World chapter Earth par paaye jaane wale organisms ki vividhta (diversity) ko explore karta hai.
- Living organisms mein kuch common characteristics hote hain: growth, movement, respiration, nutrition, excretion, reproduction, aur response to stimuli.
- Non-living cheezein — jaise rock, chair, cloud — inme se koi bhi characteristic permanently nahi dikhaate.
- Virus ek unique case hai — host cell ke bahar non-living jaisa, andar living jaisa behave karta hai, isliye ise living aur non-living ke boundary par rakha jaata hai.
- Organisms apne habitat (desert, aquatic, mountain, polar) ke hisaab se special adaptations develop karte hain — jaise cactus ke spines, fish ke gills, yak ka thick fur.
- Diversity sirf animals tak limited nahi hai — plants, fungi, aur microorganisms bhi is diversity ka hissa hain, aur har group ki apni unique jeevan-shaili (way of life) hai.
Ye chapter poore Class 6 Science Curiosity book ki biology-based chapters ("Mindful Eating", "Living Creatures: Exploring their Characteristics", "Nature's Treasures") ki neev hai — jaise Chapter 1 pure book ke liye scientific-thinking ki neev daalta hai.
In-Text Questions — Solutions
Q1. Living organisms ke koi paanch characteristics likho.
Growth, movement, respiration (breathing), nutrition (food lena), aur reproduction (offspring paida karna) — ye paanch main characteristics hain jo har living organism dikhata hai.
Q2. Kya cloud ek living cheez hai? Reason do.
Nahi, cloud non-living hai. Cloud badalta hai (shape/size change hota hai) lekin ye growth, reproduction ya respiration nahi dikhata — iska movement sirf wind ki wajah se hota hai, apne aap nahi.
Q3. Cactus me spines kyun hote hain, patte kyun nahi?
Desert me paani bahut kam milta hai. Agar cactus ke normal broad patte hote toh transpiration (paani ka evaporate hona) bahut zyada hota. Isliye patte spines me convert ho gaye — jisse surface area kam ho jaata hai aur water loss minimum hota hai. Photosynthesis ka kaam ab thick, green stem karti hai.
Q4. Fish paani ke andar saans kaise leti hai?
Fish ke paas gills hoti hain jo paani me dissolved oxygen ko absorb karti hain aur carbon dioxide bahar nikaalti hain — isi tarah fish paani ke andar respire karti hai, jaise hum lungs se hawa se oxygen lete hain.
Exercise Questions — Solutions (Q1–Q6)
1. Classify the following into living aur non-living: rock, mushroom, chair, cactus, coral, cloud.
Living: mushroom, cactus, coral (coral polyps living organisms hote hain, chahe reef ki structure rock jaisi dikhe).
Non-living: rock, chair, cloud — inhone koi bhi characteristic of life (growth, reproduction, respiration) nahi dikhaya.
2. Virus ko living aur non-living ke boundary par kyun rakha jaata hai? Explain karo.
Virus akele, host cell ke bahar, reproduce nahi kar sakta aur koi metabolism nahi dikhata — isliye non-living jaisa behave karta hai.
Lekin jaise hi virus kisi host cell ke andar jaata hai, apni genetic material use karke naye viruses banane lagta hai — isliye living jaisa bhi behave karta hai. Dono properties hone ki wajah se ise living aur non-living ke boundary par rakha jaata hai.
3. Habitat-based adaptation ka ek-ek example do: (a) desert plant (b) aquatic animal (c) mountain animal.
(a) Desert plant (cactus): Patte spines me convert ho jaate hain (water loss kam karne ke liye), stem thick aur fleshy hoti hai jo photosynthesis bhi karti hai aur paani store bhi karti hai.
(b) Aquatic animal (fish): Gills se paani me dissolved oxygen lete hain, streamlined body swimming me help karti hai.
(c) Mountain animal (yak): Thick fur coat cold se bachata hai, bada lung capacity thin, low-oxygen air me saans lene me madad karti hai.
4. Ek student kehta hai, "Fungi plants hain kyunki wo move nahi karte." Kya aap agree karte ho? Justify karo.
Nahi, ye statement galat hai. Fungi (jaise mushroom, yeast, mould) plants nahi hain kyunki:
- Fungi me chlorophyll nahi hota, isliye ye apna khana khud nahi bana sakte (plants photosynthesis karte hain).
- Fungi saprophytic hote hain — ye dead ya decaying organic matter se nutrients absorb karke jeete hain.
- Isliye sirf 'na hilna' (immobility) kisi cheez ko plant nahi bana deta — classification cell structure aur nutrition mode par depend karti hai.
5. Polar region (jaise Arctic) me rehne wale animals kis tarah ke adaptations dikhaate hain? Do examples do.
Polar animals extreme cold se bachne ke liye special adaptations dikhaate hain:
- Polar bear: Thick fur aur ek moti fat layer (blubber) body heat ko bahar jaane se rokti hai; white color snow me camouflage deta hai.
- Penguin: Waterproof feathers aur fat layer cold water me bhi body warm rakhti hai; ye groups (huddles) me rehte hain taaki collective warmth mile.
6. Diagram ke through samjhao: ek pond ecosystem me kam se kam 4 different types ke living organisms kaunse ho sakte hain?
Ek pond ecosystem me diversity dikhane wale organisms:
- Plants: Lotus, algae (paani ki satah par ya andar)
- Animals: Fish, frog
- Insects: Dragonfly, water strider
- Microorganisms: Bacteria, protozoa jo paani me decomposition ka kaam karte hain
Ye sab milkar dikhaate hain ki ek chhota sa habitat bhi kitni diversity contain kar sakta hai.
Important Equations — Ek Nazar Me
| Concept | Key Point / Rule |
|---|---|
| Characteristics of Living Organisms | Growth + Movement + Respiration + Nutrition + Excretion + Reproduction + Response to Stimuli |
| Virus — Special Case | Outside host = non-living behaviour; Inside host = living behaviour (reproduces) |
| Desert Adaptation (e.g. cactus) | Leaves → spines (reduce water loss); thick stem stores water + does photosynthesis |
| Aquatic Adaptation (e.g. fish) | Gills for respiration; streamlined body for swimming |
| Polar/Mountain Adaptation | Thick fur/fat layer for insulation; large lungs for low oxygen (high altitude) |
| Fungi vs Plants | Fungi lack chlorophyll → saprophytic nutrition; Plants have chlorophyll → autotrophic (photosynthesis) |

Common Mistakes — Yahan Marks Kat te Hain
- Students often galti se cloud, fire, ya river ko 'living' bol dete hain sirf isliye ki wo move ya change karte hain — lekin sirf movement living hone ke liye kaafi nahi hai; growth, reproduction, aur respiration bhi zaroori hain.
- Virus ko purely 'living' ya purely 'non-living' bol dena galat hai — correct answer hamesha 'boundary/borderline case' hona chahiye, dono properties ka mention karke.
- Coral ko 'non-living rock' samajh lena common mistake hai — coral reef ek living organism (coral polyps) se bani hoti hai, sirf uska calcium carbonate skeleton hard/rock-jaisa dikhta hai.
- Fungi ko 'plant' ki category me daal dena — fungi me chlorophyll nahi hota aur ye saprophytic hote hain, jabki plants autotrophic hote hain (apna khana khud banate hain).
- Adaptation aur habitat ko mix-up kar dena — habitat woh JAGAH hai jahan organism rehta hai, aur adaptation woh SPECIAL FEATURE hai jo organism us jagah survive karne ke liye develop karta hai.
- Exam me sirf ek adaptation likh dena jab question 'characteristics' poochta hai — poora list (growth, movement, respiration, nutrition, excretion, reproduction, response to stimuli) yaad rakhna zaroori hai kam-se-kam 4-5 points ke liye.
Board-Style Important Questions
- Class 6 Science Curiosity ek naya 2026-27 rationalised syllabus book hai, isliye is chapter ke koi official previous-year board/CBSE exam papers currently publicly documented nahi hain.
- School-level unit tests aur term exams me is chapter se 'characteristics of living organisms list karo' type questions frequently puchhe jaate hain — exact marks-weightage school ke apne assessment pattern par depend karta hai.
- Habitat-based adaptation wale diagram-based questions (desert/aquatic/mountain animal ka ek feature aur reason likho) school assessments me common pattern hai.
- Assertion-Reason type questions virus ke 'living vs non-living' boundary case par based ho sakte hain — concept clearly samajhna zaroori hai.
- Since ye chapter naya hai, students ko purane NCERT (pre-2026-27) syllabus ke 'Components of Food' ya 'Body Movements' jaise chapters se confuse nahi hona chahiye — wo topics is naye Curiosity book me restructure ho chuke hain.
Aksar Poochhe Jaane Wale Sawaal
Class 6 Science Curiosity chapter 2 'Diversity in the Living World' ka main topic kya hai?
Ye chapter batata hai ki living organisms ko non-living se kaise pehchane (characteristics of life ke through), aur duniya bhar ke jeev-jantu apne alag-alag habitats (desert, water, mountain, polar) ke hisaab se kis tarah adaptations develop karte hain.
Living aur non-living cheezon me main farak kya hai?
Living organisms growth, movement, respiration, nutrition, excretion, reproduction, aur response to stimuli dikhate hain. Non-living cheezein (jaise rock, chair) inme se koi bhi property permanently nahi dikhati, chahe wo change ya move bhi ho jaayein (jaise cloud).
Virus living hai ya non-living?
Virus dono ke boundary par hai. Host cell ke bahar ye non-living jaisa behave karta hai (koi metabolism nahi), lekin host cell ke andar jaake ye reproduce karne lagta hai, jo living characteristic hai.
NCERT Class 6 Science Curiosity book me total kitne chapters hain, aur ye purane syllabus se kaise alag hai?
2026-27 rationalised syllabus wali Curiosity book me total 12 chapters hain. Ye purani NCERT Science book se structure aur naming dono me alag hai — jaise purana 'Components of Food' ab 'Mindful Eating' ban gaya hai, aur Social Science topics (History, Geography, Civics) ab is Science book ka hissa nahi hain — wo alag 'Exploring Society' book me cover hote hain.
Diversity in the Living World chapter agle chapters se kaise connect hota hai?
Ye chapter foundation set karta hai jo aage 'Living Creatures: Exploring their Characteristics' chapter me detail me explore hota hai. Isi tarah 'Mindful Eating' chapter bhi living organisms ki nutrition-related characteristic ko aage badhata hai.
Is chapter ke notes PDF format me kahan milenge?
Official NCERT PDF ncert.nic.in se free download ho sakti hai. Iske alawa is tarah ke structured Hinglish notes (jaise ye content spec) chapter-wise summary, exercises, aur FAQs ke saath self-study ke liye useful hote hain.
