Respiration

The process of generating energy from the oxidation of organic compounds, with the electrons transferred to oxygen as the final electron acceptor.

Living organisms convert organic matter to carbon dioxide, releasing energy and consuming oxygen.

Autotrophic Respiration

Respiration by photosynthetic organisms such as plants and algaes.

Heterotrophic Respiration

The conversion of organic matter to CO2 by organisms other than plants.
