Biodiversity (biomes): In which biome is the greatest variety of plant and animal species typically found? Focus on global patterns of species richness. Choose the correct biome.

Difficulty: Easy

Temperate grasslands
Tropical moist forests (rainforests)
Tundra regions
Hot deserts

Correct Answer: Tropical moist forests (rainforests)

Explanation:

Concept/Approach
Global species richness peaks in tropical moist forests (rainforests) due to stable climate, high productivity, niche diversity, and long evolutionary time without glaciation.

Elimination
• Temperate grasslands/tundra/deserts have much lower species richness compared with tropical rainforests.

Final Answer
Tropical moist forests (rainforests)
