The greatest diversity of animal and plant species occurs in?

The greatest diversity of animal and plant species occurs in tropical rainforests. These regions, found near the equator, have exceptionally high species richness and biodiversity. Factors contributing to this diversity include stable climate conditions, high annual rainfall, and complex ecological interactions over millions of years. Tropical rainforests support a wide variety of plants, animals, insects, and microorganisms, many of which are endemic (found nowhere else) to specific rainforest habitats. Protecting tropical rainforests is crucial for conserving global biodiversity and maintaining ecosystem services essential for human well-being.
