Aerobic

Refers to either an environment that contains molecular oxygen gas (O2); an organism or tissue that requires oxygen for its metabolism ; or a chemical or biological process that requires oxygen. Aerobic organisms use molecular oxygen in respiration , releasing carbon dioxide (CO2) in return. These organisms include mammals, fish, birds, and green plants, as well as many of the lower life forms such as fungi , algae, and sundry bacteria and actinomycetes. Many, but not all, organic decomposition processes are aerobic; a lack of oxygen greatly slows these processes.
