Correct Answer:
C. Tropical Rainforest
The Tropical Rainforest biome exhibits the greatest biodiversity on Earth. These regions, characterized by high temperatures, abundant rainfall, and consistent sunlight year-round, provide stable and favorable conditions that support an immense variety of plant and animal life. They cover a small percentage of the Earth's land but harbor over half of the world's species.
- Deserts have extreme conditions and scarce water, limiting biodiversity.
- Tundra regions are cold with permafrost and short growing seasons, resulting in low biodiversity.
- Grasslands, while supporting large animal populations, generally have lower overall species diversity compared to rainforests due to less complex vegetation structure and seasonal variations.
