Abiotic Factor
Non-living physical or chemical components of an environment that affect living organisms.
Real World
In Death Valley, California, summer ground temperatures exceed 70°C, making it inhospitable to most plant life — only extremophiles and specially adapted species like creosote bush survive these harsh abiotic conditions.
Exam Focus
Always distinguish abiotic from biotic factors; examiners penalise listing 'food' without specifying it as a biotic interaction.
