Verified step by step guidance1
Understand the concept of abiotic factors: Abiotic factors are non-living components of an ecosystem that influence living organisms. Examples include temperature, sunlight, water, and soil.
Identify the key characteristic of the Sahara Desert: The Sahara Desert is known for its extreme environmental conditions, including high daytime temperatures, low precipitation, and sandy terrain.
Differentiate between biotic and abiotic factors: Biotic factors refer to living organisms, such as scorpions, cactus plants, and fennec foxes. Abiotic factors, on the other hand, are non-living elements like temperature, sunlight, and soil composition.
Analyze the options provided: Scorpions, cactus plants, and fennec foxes are all living organisms, making them biotic factors. High daytime temperatures, however, are a non-living environmental condition, making it an abiotic factor.
Conclude that high daytime temperatures are an abiotic factor in the Sahara Desert because they represent a non-living environmental condition that impacts the ecosystem.
