Meher ki library kitaabon ko vishay se group karti hai taaki aasaani se milein. Scientists jeevon ke saath bhi yahi karte hain: unhe saajhi visheshtaon (features) se group karte hain, jaise tane ki kism, pairon ki ginti, ya kahan rehte hain.

Jaanwaron ko pairon ki ginti se group kar sakte hain: koi nahi (saanp, kenchua), do (murgi, kabootar), chaar (bakri, kutta), chhah (cheenti, titli) ya aath (makdi). Ya kaise chalte hain se: chalna, rengna, udna, tairna, koodna.

Ek hi jaanwar alag feature chunne par alag groups mein ja sakta hai. Battakh chalti, tairti aur udti hai! Isliye batana padta hai kaunsa feature use kar rahe hain. Kahan rehte hain se: zameen, paani, ya dono (medhak, kachhua).

Grouping se hum jeevan ki badi vividhta ko padh paate hain, features yaad rakhte hain, aur dekhte hain ki jeev aapas mein kaise jude hain. Ek jaise features wale jaanwaron mein aur bhi bahut kuch saajha hota hai: sab chidiyon ke pankh, chonch hote hain aur ande dete hain.

Explore: jaanwaron ko do alag tareekon se group karo.

1. Kahan rehte hain, us se group karo.
2. Ab in jaanwaron ko pairon ki ginti se group karo.

Yaad rakho

• Hum jeevon ko saajhi visheshtaon se group karte hain.
• Ek hi jeev alag features ke liye alag groups mein ho sakta hai.

Quick check

Jaanwaron ko group karte waqt kaunsa feature use kar rahe hain ye kyun batana chahiye?

1. Ek hi jaanwar alag features ke liye alag groups mein aa sakta hai
2. Jaanwar roz badalte hain
3. Sirf ek grouping sambhav hai
4. Features se farak nahi padta

Socho

In jaanwaron ko do groups mein baantne ka tareeka socho: kauwa, gaay, chamgaadad, billi, gauraiya, bakri. Kya ek se zyada tareeke hain?
