What is metabolic rate?

State 3 ways metabolic rate can be measured.
- oxygen consumption per unit of time
- carbon dioxide production per unit of time
- heat production per unit of time
Put the following in order of highest to lowest metabolic rates:
a) fish
b) mammals and birds
c) amphibians and reptiles
b) mammals and birds
c) amphibians and reptiles
a) fish
