What term represents the combination of biotic and abiotic factors?

The term that represents the combination of biotic (living) and abiotic (non-living) factors is "ecosystem." An ecosystem encompasses all the organisms interacting with each other (such as plants, animals, fungi, and microorganisms) and their physical environment, which includes elements like soil, water, sunlight, and climate. This interaction forms a complex network where energy flows and nutrients cycle, sustaining life and contributing to various ecological processes.

The concept of an ecosystem highlights how living organisms are not isolated but are part of a larger system where both living (biotic) and non-living (abiotic) components influence and depend on one another. In this context, biotic factors such as predation, competition, and symbiosis play significant roles alongside abiotic factors like temperature, pH levels, and nutrient availability.

Understanding the definition of an ecosystem is crucial as it underscores the interconnections between organisms and their environment, which are vital for biodiversity and ecological health.
