Farhan ka cousin registaani shehar mein rehta hai, aur Nisha ki bua barfeele pahaadon mein upar. In jagahon ke paudhe aur jaanwar bahut alag dikhte hain! Har jeev ka ek habitat hota hai: jahan wo prakritik roop se rehta hai aur khaana, paani, aashray paata hai.
Registaan: oont ke lambe pair aur chaude talve ret mein nahi dhanste, aur wo kai din bina paani reh sakta hai. Cactus mote tanon mein paani jama karta hai aur chaude patton ki jagah kaante hote hain, taaki kam paani udde.
Pahaad: yak ke lambe ghane baal garmi rakhte hain. Cheed aur deodar ke ped shankh jaise aakaar ke, sui jaise patte, taaki barf phisal jaaye. Paani: machhli ke fins tairne aur gills saans ke liye; kamal ke patte tairkar dhoop tak pahunchte hain.
Jo features kisi jeev ko uske habitat mein jeene mein madad karein unhe adaptations kehte hain. Bhaarat mein Himalaya se samudra tak bahut tarah ke habitats hain, isliye bahut badi biodiversity hai: kisi jagah ke saare paudhon aur jaanwaron ki vividhta.
Jab jungle kat-te hain ya nadiyaan gandi hoti hain, habitat khatam hote hain aur kuch jeev durlabh ho jaate hain. National parks, wildlife sanctuaries aur pavitra van (gaon dwara bachaaye jungle ke hisse) habitat surakshit rakhte hain. Hum bhi madad kar sakte hain: ped lagao, paani bachao aur kabhi kachra mat phenko.
Explore: har jeev ko uske ghar se milao.
- Har ek ko uske habitat mein sort karo.
Yaad rakho
- Habitat wo jagah hai jahan jeev prakritik roop se rehta hai. Wahan jeene mein madad karne wale features adaptations hain.
- Biodiversity kisi jagah jeevan ki vividhta hai. Parks, sanctuaries aur pavitra van ise bachaate hain.
Quick check
Cactus mein chaude patton ki jagah kaante kyun hote hain?
- Sookhe registaan mein kam paani khone ke liye
- Machhli pakadne ke liye
- Barf mein garam rehne ke liye
- Kyunki paani mein rehta hai
Answer
Sookhe registaan mein kam paani khone ke liye. Chaude patte bahut paani khote hain. Kaante cactus ko paani bachaane mein madad karte hain: ek adaptation.
Socho
Agar oont ko barfeele pahaad par le jaayein, to use kya mushkilein aayengi? Uske kaunse features wahan kaam nahi aayenge?
Ek answer
Use bahut thand lagegi, kyunki yak jaise lambe ghane baal nahi, aur chaude talve narm ret ke liye bane hain, barf ke liye nahi. Bina paani rehne ki kshamata wahan kaam ki nahi jahan paani bahut hai. Iske adaptations registaan ke liye hain, pahaad ke liye nahi.
