Which of the following terms best describes the role of abiotic factors in ecosystems?

Abiotic factors refer to the non-living components of an ecosystem that influence the environment and the organisms that live in it. These factors include elements such as temperature, water, sunlight, soil, and atmospheric gases. By being categorized as external environmental components, abiotic factors play a critical role in shaping the habitat and the living conditions for organisms. They affect things like nutrient availability, habitat structure, and the overall functioning of the ecosystem.

The understanding that these factors are external highlights their influence as forces that operate within and upon the ecosystem, shaping not only the environment itself but also the interactions among species and the overall biodiversity. While abiotic factors do affect species interactions, they do not solely determine them, as biotic factors (the living organisms) also play a significant role in those interactions. Therefore, recognizing the role of abiotic factors as external components provides a comprehensive understanding of their impact on ecosystems.
