Which biome is known for having the most biodiversity on Earth?

The tropical rain forest is recognized for having the most biodiversity on Earth due to its warm temperatures, high levels of precipitation, and stable climate conditions throughout the year. These factors create an ideal environment for a vast array of plant and animal species to thrive. The complex structure of the rainforest, with multiple layers (such as the canopy, understory, and forest floor), allows for a wide variety of niches that different organisms can occupy, further enhancing species richness. Additionally, tropical rain forests support a greater number of unique ecosystems and numerous endemic species that cannot be found anywhere else, contributing to their distinction as a biodiversity hotspot. This immense variety plays a crucial role in global ecological processes and helps to maintain the Earth's overall health.
