* Sunlight: Provides energy for photosynthesis, the foundation of most ecosystems.
* Water: Essential for all living organisms, involved in chemical reactions, and a major component of the environment.
* Air: Provides oxygen for respiration and carbon dioxide for photosynthesis.
* Temperature: Affects the rate of biological processes and the types of organisms that can survive.
* Soil: Provides nutrients, water retention, and a physical substrate for plants.
* Minerals: Essential nutrients for plant growth, absorbed from the soil.
* Rocks and Topography: Influence water flow, soil composition, and habitat availability.
* Climate: The overall weather patterns in a region, including temperature, precipitation, and wind.
These abiotic factors interact with each other and with the living organisms (biotic factors) in an ecosystem to create a complex and dynamic system.
