What’s the definition of abiotic factor?

Abiotic factors can be climatic, related to weather, or edaphic, related to soil. Climatic factors include air temperature, wind and rain. Edaphic factors include geography such as topography and mineral content, as well as soil temperature, texture, moisture level, pH level and aeration.

Climatic factors greatly impact which plants and animals can live within an ecosystem. Prevailing weather patterns and conditions dictate the conditions under which species will be expected to live. The patterns not only help to create the environment but also impact water currents. Changes in any of these factors, such as those that occur during occasional fluctuations such as El Niño, have a direct impact and can have both positive and negative effects.
