Which factor is abiotic?

• A. Predation
• B. Water
• C. Competition
• D. Temperature

Answer: (D)

Abiotic factors are non-living parts of an environment that influence how organisms live. Temperature is a non-living environmental condition that affects metabolic rates, enzyme activity, and the range of habitats that organisms can tolerate. Because it’s a physical property of the environment rather than a living thing, it fits as abiotic. Predation and competition involve living organisms, so they are biotic. Water is also non-living, but the characteristic highlighted here as a classic abiotic factor is temperature.
