Which term encompasses all non-living components of an ecosystem?

The term that encompasses all non-living components of an ecosystem is abiotic environment. This includes factors such as sunlight, temperature, water, soil, and minerals, which are essential for supporting life and influencing the interactions among living organisms. The abiotic environment plays a crucial role in determining the characteristics of an ecosystem, including what types of organisms can inhabit it and how they interact with one another.

Biotic community refers to the living organisms within an ecosystem, while population focuses specifically on a group of individuals of the same species. Community structure involves the organization and distribution of different species within a community, but it does not encompass the non-living components that are integral to the ecosystem's functioning. Thus, the abiotic environment is the most comprehensive term for all non-living aspects, making it the correct answer.
