Physical Environment
The physical environment encompasses all non-living (abiotic) components and conditions that influence and interact with living organisms within an ecosystem.
Physical Environment
The physical environment constitutes the abiotic foundation that supports and shapes all ecosystems. It represents the complex interaction of non-living factors that create the conditions necessary for life and ecological processes.
