How do living things acquire and use energy? – Respiration


  • Respiration is one of many methods that allow living things to process energy.
  • Specifically, respiration allows the cells of living things to convert sugars that they consume into usable energy.
  • Almost all living things made up of more than one cell use respiration.
  • Some living things made up of just one cell (for example: bacteria) also make use of respiration.
