Der tak chabaane par roti meethi kyun lagti, gaay chabaati kyun rehti, aur li gayi hawa hamein oorja kaise deti? Is chapter mein aahaar naal mein khaane ka safar dekhenge, iodine se starch jaanchenge, ruminant aur pakshi alag kaise pachaate dekhenge, saans ka model banaayenge, aur insaan, machhli, mendhak aur kenchue ki saans milaayenge.
Is chapter mein tum
- insaani paachan tantra mein khaane ka safar batana
- ruminant aur pakshiyon mein paachan batana
- saans, gas len-den aur shvasan samjhaana
- alag jaanwaron ke saans ke ang milaana
Topics
- Insaanon mein Paachan NCERT 9.1.1
Paachan: munh (chabaana, starch par laar) → bhojan nali → aamaashay (acid, protein) → chhoti aant (pitt, agnaashay ras, avshoshan).
- Doosre Jaanwaron mein Poshan NCERT 9.1.2
Gaay jaise ruminant ghaas rumen mein aanshik pachaakar waapas chabaate.
