• A species range represents a response to the physical environment in which all organisms live. The physical environment consists of non-living (abiotic) components such as rock, air and water, which are products of the lithosphere (rock strata), atmosphere (air masses) and hydrosphere (water bodies) of the
earth. The lithosphere, atmosphere, and hydrosphere thus impinge upon and contribute significantly to the composition of the biosphere, together with this, they make up the interacting geo system.
• A species range results from competition with other species for essential resources such as food and living space. Each species does not possess a unique range. There is a certain amount of overlap between ranges because each species does not have exclusive use of a particular resource.
• A species range is not only a result of the adaptation of species to its existing environment (animate and inanimate) but also of its evolutionary history. This history usually spans thousands or millions of years and has proceeded against a background of continuous environmental change.
