Final answer:
Different animals have varying respiratory organs. Mosquitoes have tracheae, lizards have lungs, earthworms respire through their skin, cows have lungs, and fish use gills to breathe.
Step-by-step explanation:
The respiratory organs in different animals vary depending on their anatomical adaptations to their environments.
Mosquito:
Mosquitoes have tiny, tube-like structures called tracheae that deliver oxygen directly to their cells.
Lizard:
Lizards breathe using lungs, similar to humans. They inhale air through their nostrils, and the oxygen enters their lungs.
Earthworm:
Earthworms do not have lungs. Instead, they respire through their moist skin, which allows oxygen to diffuse into their bloodstream.
Cow:
Cows are mammals, and like most mammals, they have lungs for respiration. They inhale air through their nostrils and the oxygen enters their lungs.
Fish:
Fish respire through gills, which are feathery structures located on the sides of their head. Gills extract oxygen from water as it flows over them.
