Answer 1

the respiratory organ for fish is giils and the rest I don't know so you should refer to Google.

Answer 2

Flatworms and the Earthworms breathe via their skin, unlike the mammals. Fish breathe underwater via gills. Prawn breathes via gill-like structures outside the body.

Cockroaches use neither gills nor the lungs. They breathe via a system of tubes connected to the spiracles. Cats breathe via lungs, just like us humans.
