2. Describing disease processes presumed to be a result of the progressive loss of vitality of certain tissues or organs leading to physical disorders or the loss of bodily functions.
2. Progressive loss of vitality of certain tissues or organs leading to disorders or losses of functions: The abiotrophy of the heart may be appreciably shorter than that of other organs of the body which can lead to early disturbances in activities that upset other bodily organs.
2. Relating to that branch of biology which deals with the distribution of living organisms by air, either the exterior, or outdoor air (extramural aerobiology), or the indoor air (intramural aerobiology).
2. Living, or existing, only in the air or free oxygen.
3. An environment in which the partial pressure of oxygen is similar to normal atmospheric levels.
4. Life which is sustainable by means of atmospheric oxygen.

Another allobiosphere has been discovered at the bottom of the seas where hot springs come up from that part of the Earth that is deep below the surface or on the seafloor where hot springs have animals that are separate from green plants but that depend on bacteria that utilize the energy of chemicals from the hot springs.
Ocean depths are the most extensive and permanent example of the allobiosphere where in great areas there is no light and so there is no active plant life; however, explorers of the depths of the oceans have discovered various animals; such as, worms, prawn-like creatures, and many types of fish that live in these locations.
The ecologist, G. Evelyn Hutchinson, coined the term allobiosphere for these environments, where plant life and its photosynthesis are replaced by environmental extremes of darkness, heat, or cold, but where life continues, life that depends for nourishment from materials that come from other places.
