Detailed explanation-1: -In conditions favorable to life, halophilic archaea are generally aerobic chemoheterotrophs. However, when exposed to certain conditions they exhibit different modes of energy generation and even anaerobic growth in the absence of oxygen.

Detailed explanation-2: -Chemoheterotrophs are the most abundant type of chemotrophic organisms and include most bacteria, fungi and protozoa.

Detailed explanation-3: -Aerobic chemoautotrophs include organisms that oxidize H2, CO, NH4+, NO2−, elemental S, H2S or Fe2+ using O2. Anaerobic chemoautotrophs include organisms that derive energy from the reduction of CO2 to CH4, or of SO4−− to H2S.

Detailed explanation-4: -For instance, human beings undergo the process of respiration by inhaling oxygen gas and exhaling carbon dioxide gas. Many other living organisms including plants and animals undergo respiration process to obtain energy for their metabolic activities.
