What term describes the combination of living and non-living elements in an ecosystem?

The term that describes the combination of living and non-living elements in an ecosystem is "Ecosystem Components." In ecology, the components of an ecosystem are categorized into biotic factors, which include all living organisms (plants, animals, fungi, and microorganisms), and abiotic factors, which encompass non-living elements such as air, water, soil, sunlight, and climate. Together, these components interact with each other to form a dynamic system.

Understanding this term is crucial because it encapsulates the complexity of ecosystems as it recognizes the interdependence of living organisms and their physical environment. This synergy is what sustains biodiversity and ecological balance. The other options focus on specific aspects—biotic factors and abiotic factors refer individually to living and non-living components, while system dynamics pertains to the interactions and processes within a system rather than the elements themselves. Therefore, "Ecosystem Components" is the most appropriate term to describe the integral combination of both living and non-living elements within an ecosystem.
