Which feature best describes a desert biome?

• A. Very dry climate
• B. High day temperatures
• C. Low night temperatures
• D. Flora with water storage

Answer: (A)

Desert biomes are defined by an extremely dry climate, meaning very low rainfall. That scarcity of water drives the ecosystem’s structure more than any single temperature pattern. The limited precipitation limits plant growth and animal activity, leading to sparse vegetation and many water-conserving adaptations. While hot daytime temperatures are common in many deserts, and some deserts have cold nights, dryness is the most consistent and distinctive feature across desert biomes. The idea of water-storing plants arises because of that dryness, but it’s an adaptation, not the defining feature of the biome itself.
