How Abiotic Factors Shape Life on Earth Life on Earth depends on far more than plants and animals alone. Hidden behind every forest, ocean, desert, and mountain ecosystem are powerful nonliving forces that determine whether organisms can survive or disappear. These forces are known as abiotic factors , and they play a central role in shaping biodiversity, food chains, migration patterns, and the overall balance of nature. Temperature, water availability, sunlight, soil quality, oxygen concentration, salinity, and climate patterns influence every living organism on the planet. Even the smallest environmental change can affect entire ecosystems. Some species adapt successfully, while others struggle to survive. Understanding abiotic factors helps scientists explain how ecosystems function and why environmental changes such as global warming, droughts, and pollution threaten life on Earth. In ecology, abiotic factors are considered the foundation of every habitat. Without suitabl...
