This semester we will devote our attention to studying the abiological processes of certain non-living organisms.
It may be that in the progress of science it may yet become possible to construct living protoplasm from non-living material.
The soil and the rocks under it form the non-living substratum for all ecosystem components to exist on.
Animals and plants as agents of disease or injury form part of the larger subject of the struggle for existence between living organisms, as is recognized even by those who do not so readily apprehend that diseased conditions in general are always signs of defeat in the struggle for existence between the suffering organism and its environment, living and non-living.
Creature simulators have a lot in common with environment simulators; however, they focus more on the living creatures involved than on the non-living resources.
