Definition - What does Physical or Abiotic Factors mean?
Any environmental factor not caused by living organisms is referred to as an abiotic or physical factor.

Safeopedia explains Physical or Abiotic Factors
Non-living resources impact ecosystems and a change in the parameters of these resources directly effects the living organisms within an ecosystem. Physical or abiotic factors determine what organisms will be able to thrive within an ecosystem and ultimately determine its biotic (living) composition. Essentially, this includes geology, soil, air quality, minor topographical features, available water and water quality, temperature, precipitation volume and type, prevailing winds and their velocity, sun exposure and humidity.
