Ellen Williams answered on 14 Mar 2017:
Both frogs and humans need oxygen in order to breathe – but the way they get their oxygen is slightly different. As humans we breathe only through our lungs. Frogs also breathe through their lungs but they can also breathe through their skin! I guess they may physically need less oxygen because they are cold blooded animals and so have a lower metabolic rate (although that is a guess, so apologies if it is wrong, just applying the limited knowledge i still have from school :))

Both humans and amphibians need oxygen in order to provide energy. However, energy can be provided without oxygen too, also known as anaerobic respiration, and both humans and amphibians have this form of respiration. Nevertheless, amphibians can do anaerobic respiration to a larger extant (compared to humans) because they sometimes live in areas with low oxygen content, like muddy waters.

HI Julen, I think Ellen and Cedric have explained this really well already so i don’t think I can add much more

Humans need more oxygen than amphibians because we are bigger. But amphibians can get oxygen through their skin as well as through their lungs. Their skin needs to be wet for this to work. We humans can only get oxygen from our lungs.

In addition to everyone else’s answers (which were really great) to this question, I think it’s also because they are not warm blooded. We are warm-blooded and this requires more energy and a faster metabolism , which in turn requires more oxygen. Amphibians and reptiles have slower metabolisms compared to mammals like us, and therefore, need less oxygen.
