Animals require oxygen directly for respiration, to convert fuels in their bodies into energy via a reaction which involves oxygen.
Plants and other lifeforms require oxygen indirectly as a component of many chemicals which make up their cellular structure and the compounds they use to create energy from.
Not all living things have lungs -- but all living things utilize energy in some fashion.
Considering that plants are also living things we all need oxygen, so all living things breath.
