In the context of terrestrial biomes in northern regions, which set lists three abiotic (nonliving) factors characteristic of an Arctic ecosystem?

• A. Low temperatures, permafrost, and low precipitation
• B. Coral reefs, warm ocean currents, and high salinity
• C. High temperatures, abundant rainfall, and fertile soils
• D. Dense tree canopy, high humidity, and frequent wildfires

Answer: (A)

Verified step by step guidance

1. Understand that abiotic factors are nonliving physical and chemical elements in an ecosystem, such as temperature, soil type, water availability, and sunlight.
2. Identify the characteristics of an Arctic ecosystem, which is a terrestrial biome found in northern regions with extreme cold conditions.
3. Recall that Arctic ecosystems typically have low temperatures due to their high latitude and proximity to the poles.
4. Recognize that permafrost, which is permanently frozen ground, is a key abiotic feature unique to Arctic regions.
5. Note that precipitation in Arctic ecosystems is generally low, often in the form of snow, making low precipitation another important abiotic factor.
