Frog ka life cycle kya hai?
Short mein jawab
Frog ke life cycle mein chaar stages hain. Ande paani mein jelly jaise guchhe, spawn, mein diye jaate hain, aur andar embryo banta hai. Tadpole pehle poonchh ke saath bina pair ke hote hain, phir pichhle pair aate hain. Froglet zameen pe aane lagte hain, aur lagbhag 14 hafte mein bina poonchh ke adult frog ban jaate hain.

Talaab ki sair
Baarish ke mausam mein pedon aur oonchi ghaas se ghira ek uthla talaab jeevan se bhara hota hai. Kisi teacher ya bade ke saath jao, poori baanh ki shirt aur poori pant pehno, aur bina kuch chhede door se dekho. Talaab ke kinaare paani pe tairta ya paani ke paudhon se chipka ek safed, jelly jaisa padaarth dikh sakta hai. Ye frog ke andon ka guchha hai, jise spawn kehte hain.
Talaab mein frog ke stages
Aise talaab mein ek hi samay pe frog ke kai alag stages dikh sakte hain:
- jelly mein ruke, kaale dot wale gol andon ka guchha (spawn);
- ande jinke andar chhote comma jaise embryo hain;
- gol shareer aur lambi poonchh wala tadpole, bina pair ke;
- waisa hi tadpole, par do pichhle pairon ke saath;
- froglet, jo chaar pair aur chhoti poonchh wala chhota frog lagta hai;
- patte pe baitha bina poonchh ka adult frog.
Inhe kram mein lagaane ke liye socho ki kaun si shape kis mein badal sakti hai: ande embryo bante hain, embryo se tadpole nikalte hain, tadpole ke pair aate hain, wagairah.
Frog ka life cycle
Chapter in kadmon ko chaar stages mein rakhta hai:
| Stage | Kaisa dikhta hai | Kab |
|---|---|---|
| I: Egg (spawn, phir embryo) | Jelly mein ande; andar embryo banta hai | Din 1; embryo din 3–4 tak |
| II: Tadpole | Pehle poonchh, pair nahi; phir pichhle pair bhi | Din 7–10; pair 8–10 hafte tak |
| III: Froglet | Chhoti poonchh wala chhota frog | Lagbhag 12 hafte |
| IV: Adult frog | Poora bada frog, poonchh nahi, mazboot pair | Lagbhag 14 hafte |
Egg stage sabse chhota hai: lagbhag 10 din ke andar andon se tadpole nikal aate hain. Tadpole stage sabse lamba hai, kai hafte chalta hai.
Frog kaise badalta hai
Tadpole paani mein rehte hain, aur unki poonchh unhe tairne mein madad karti hai. Badhte hue unke pair aate hain par kuch samay poonchh bhi rehti hai. Dheere-dheere wo chhote frog jaise dikhne lagte hain, jinhe froglet kehte hain. Froglet abhi bhi paani mein rehte hain par zameen pe kuch samay bitaane lagte hain. Wo badhte rehte hain, unki poonchh poori tarah chali jaati hai, aur unke pair kudne aur zameen pe utarne ke liye mazboot ho jaate hain. Wo adult frog bante hain jo paani aur zameen dono pe rehte hain. Is tarah life cycle mein frog ki shape, shareer ke hisse aur ghar tak badal jaata hai.
Frog aur machchhar
Machchhar bhi badhte hue poori tarah badal jaata hai, chaar stages se guzar ke: egg, larva, pupa aur adult. Dono jaanwar paani mein ya paani ke paas ande dete hain, aur unke chhote stages paani mein rehte hain. Par machchhar mein pupa stage hota hai aur adult udta hai, jabki frog ke pair dheere-dheere aate hain aur adult paani aur zameen ke beech phudakta hai.
Kya pakshi aise badalte hain?
Aise nahi. Ande se nikla chooza pehle se hi chhota pakshi dikhta hai; wo bas bada hota hai aur uske bade pankh aa jaate hain. Frog aur machchhar alag stages mein bilkul alag dikhte hain. Aise badlaav unhe jeene aur apni jaati aage badhaane mein madad karte hain, isliye hamein unki aur unke talaabon aur wetlands ki dekhbhaal karni chahiye. Living beings ke saare stages dekho Chapter 10 notes mein.

Tadpole ke liye poonchh ka kya fayda hai?
Jawab dekho
Jawab: Poonchh tadpole ko paani mein tairne mein madad karti hai, jahan wo rehta hai, taaki wo ghoom sake, khaana dhoondh sake aur khatre se bach sake. Jab frog ke pair aa jaate hain aur wo zameen pe bhi rehne lagta hai, to poonchh ki zaroorat nahi rehti.

Jawab: Dono paani mein ya paani ke paas ande dete hain, unke chhote stages paani mein rehte hain, aur adult banne se pehle unka shareer bahut badalta hai.
Students ke sawal
Frog ke life cycle ke stages kaun se hain?
Egg stage (spawn, jisme embryo banta hai), tadpole stage (pehle poonchh ke saath aur bina pair, phir pichhle pairon ke saath), froglet stage aur adult frog stage.
Spawn kya hai?
Spawn ek safed, jelly jaisa padaarth hai jo talaab ke kinaare paani ki satah pe ya paani ke paudhon se chipka milta hai. Ye asal mein frog ke andon ka guchha hai.
Kya frog apne life cycle mein ghar badalta hai?
Haan. Ande, embryo aur tadpole sirf paani mein rehte hain. Froglet paani mein rehte hain par zameen pe kuch samay bitaane lagte hain, aur adult frog paani aur zameen dono pe rehte hain.
Frog ka anda murgi ke ande se kaise alag hai?
Frog ke ande chhote, naram aur bina sakht chhilke ke hote hain, aur bahut saare ek saath paani mein jelly mein diye jaate hain. Murgi ek baar mein ek bada, sakht chhilke wala anda zameen pe deti hai.
