Q

What are the three examples of how organisms use the energy transferred by respiration?

A

1) to build up larger molecules from smaller ones
2) in animals it is used to allow the muscles to contract (so they can move about)
3) in mammals and birds the energy is used to keep their body temperature steady in colder surroundings.
