Video narration
Kya is khidki ke paas rakhe paudhe ka khana mitti se aata hai? Paani ki kami mein yah murjhata hai aur roshni ki or badhta hai, isliye lagta hai ki iska khana mitti ya dhoop se seedhe aata hai. Par asli rasoi patta hai. Suraj ki roshni use urja deti hai. Jadon se aaya paani aur hawa mein maujood carbon dioxide patte tak pahunchte hain. Phir roshni ki urja se patta dono se glucose banata hai. glucose paudhe ka istemal karne yogya bhojan hai, jo uski badhat mein kaam aata hai. Is prakriya ko photosynthesis kehte hain. Saath hi oxygen hawa mein chhod diya jaata hai. To mitti taiyar khana nahin deti; vah paani aur khanij deti hai. Is khidki ka paudha bhojan ikattha nahin kar raha. Vah ek jeevit, suraj se chalne wali rasoi hai. Yaani paudha photosynthesis mein roshni se paani aur carbon dioxide ko glucose mein badalkar apna bhojan banata hai aur oxygen chhodta hai.
