Answer :
Fish:
In most fish breath happens through gills. Lungfish, in any case, have maybe two lungs. The labyrinth fish has built up an uncommon organ that enables them to exploit the oxygen of the air yet is not a genuine lung.
Mosquito:
Air enters the respiratory frameworks of insects through a progression of outside openings called spiracles. These outer openings, which go about as strong valves in a few insects, prompt the interior respiratory system, a thickly arranged cluster of tubes called tracheae.
Earthworm:
Earthworms have no extraordinary respiratory organs. Gasses are traded through the soggy skin and vessels, where the oxygen is gotten by the hemoglobin broke down in the blood plasma and carbon dioxide is discharged.
