Which terrestrial biome can be found on almost every continent?

• A. Desert
• B. Taiga (boreal forest)
• C. Tropical rainforest
• D. Tundra

Answer: (A)

Verified step by step guidance

1. Step 1: Begin by understanding the concept of a terrestrial biome. A biome is a large ecological area characterized by specific climate conditions, flora, and fauna. Terrestrial biomes are land-based biomes, as opposed to aquatic ones.
2. Step 2: Review the characteristics of each biome listed in the problem: Desert, Taiga (boreal forest), Tropical rainforest, and Tundra. Focus on their global distribution and presence across continents.
3. Step 3: Analyze the Desert biome. Deserts are defined by low precipitation and can be hot or cold. They are found on almost every continent, including Africa, Asia, North America, South America, Australia, and Antarctica (cold desert).
4. Step 4: Compare the Desert biome to the other options. Taiga is primarily found in the northern hemisphere (e.g., Canada, Russia). Tropical rainforests are concentrated near the equator (e.g., Amazon, Congo). Tundra is limited to polar regions and high altitudes.
5. Step 5: Conclude that the Desert biome is the correct answer because it is the only biome listed that is present on almost every continent, making it globally widespread.
