Abiotic refers to non-living components of an ecosystem.

This means any part of the environment that is not derived from or produced by living organisms. Examples include:

* Physical factors:

* Sunlight: Provides energy for photosynthesis.

* Temperature: Affects biological processes like enzyme activity.

* Water: Essential for all life forms.

* Air: Provides oxygen for respiration.

* Soil: Provides nutrients and support for plants.

* Minerals: Essential for plant growth and animal health.

* Chemical factors:

* pH: Acidity or alkalinity of water and soil.

* Salinity: Salt concentration in water.

* Nutrients: Available nitrogen, phosphorus, and other elements.

* Geological features:

* Landforms: Mountains, valleys, and plains.

* Rock types: Influence soil composition.

* Weathering and erosion: Shape the landscape and influence soil formation.

Abiotic factors play a crucial role in shaping the environment and influencing the distribution and survival of living organisms.
