Yes — water is an abiotic factor for biomes.
Abiotic factors are the nonliving physical and chemical components of an environment (temperature, sunlight, soil, pH, salinity, nutrients, etc.). Water — in forms such as precipitation, soil moisture, groundwater, humidity, surface water and salinity — is one of those key nonliving factors.
How water shapes biomes:
- Terrestrial: amount and seasonality of precipitation and soil moisture determine whether an area is desert, grassland, temperate forest, or rainforest and strongly influence plant types and productivity.
- Aquatic: water is the defining physical medium; salinity, depth, temperature, dissolved oxygen and nutrients differentiate marine, estuarine and freshwater biomes.
- Organisms’ distributions and adaptations (drought tolerance, water-use efficiency, salt tolerance) are driven largely by water availability.
So yes — water is an essential abiotic factor and often one of the most important determinants of biome type and ecosystem function.
