Kaun kisko khaata hai? Khaane ki kadi
Riya ke ghar ki chhat par ek gamla tha, jisme ek keeda patta khaa raha tha. Tabhi ek chidiya aayi aur keede ko le udi. Riya ne socha: 'Chidiya ne keede ko khaaya, keede ne patte ko — par patte ne kya khaaya?'
Socho pehle… phir dekho jawab
Dadi ne bataaya, 'Patte ne kuch nahi "khaaya" — usne suraj ki roshni, paani aur hawa se apna khana khud banaya!' Riya boli, 'Toh har khaane ki kadi ka pehla kadam suraj hai.'
Riya ne copy mein teer banaaye: suraj → patta → keeda → chidiya. 'Ise khaane ki kadi (food chain) kehte hain,' dadi boli. 'Isme ek jeev doosre ka khana banta hai.'
Tabhi Riya ne apna doodh ka glass dekha aur ek aur kadi banaayi. Pehle usne 'gaay' se shuru kiya, phir ruk kar aage suraj aur ghaas jode: suraj → ghaas → gaay → doodh → hum.
'Sab kadiyan suraj se hi kyun shuru?' Dadi ne kaha, 'Kyunki sirf hare paudhe suraj ki roshni se khana bana sakte hain. Jaanwar aur hum khana bana nahi sakte, sirf khaa sakte hain. Paudhe na hon, toh kadi toot jaaye.'
Riya gamle ke sookhe patte phenkne wali thi. Dadi boli, 'Kadi ka aakhri kadam mitti mein hai. Gira patta, sadta phal, chhilka — inhe mitti ke nanhe jeev khaate hain aur mitti ko phir paudhe ka khana bana dete hain.' Riya ne gamle mein sookhe patte rehne diye: 'Yeh mitti ka khana hai.'
Tum Riya hoti toh apne ghar ke aas-paas kaun si nayi kadi dhoondhti?
Humne kya kiya :- Gamle ke keede aur chidiya se peeche jaakar poori kadi dhoondi.
Isse kya hua :- Samjhe ki har kadi suraj se shuru hoti hai aur mitti par poori hoti hai.
Ghar pe try karo
Bade ke saath 10 minute kisi paudhe ya ghaas ke paas chup-chaap baitho. Jo bhi jeev dikhe — cheenti, keeda, titli, chidiya, gilahri — copy mein likho. Phir socho: kaun kya khaata hoga? Teer se kadi banao.
Wow!
Ek chhoti si cheenti bhi suraj ki roshni se chalti hai — uska khana kisi paudhe ne suraj se banaya tha!
Mummy-Papa ke liye
Aaj bachche ke saath thali ki ek cheez ki kadi peeche tak banwaaiye — dahi, doodh, gaay, ghaas, suraj — aur poochhiye: 'Agar ghaas na ho toh?'
