adjective

Abiotic means not living, or caused by things that are not alive. It is often used in science, especially in ecology and biology.

  • Sunlight is an abiotic factor.
  • Soil and water are abiotic parts of the habitat.
  • Abiotic conditions affect plant growth.

Adinary Nuance

Abiotic is used in science to mean “non-living,” especially in ecology. It is not the same as “inorganic,” which is a chemistry word, or “dead,” which means once alive but no longer alive. Writers choose abiotic when they want to talk about things like sunlight, water, temperature, or rocks in a living environment.
