Tropical climate. It is also the oldest biome in the world. I was looking for certain numbers, (how many % of species live there) but couldn't find any :(
The tropical rainforest and temperate regions, especially those with Mediterranean climates, produce the richest variety of vegetation due to their warm temperatures and high precipitation. Tropical rainforests support immense biodiversity, while Mediterranean climates host diverse shrublands. Together, these climate zones showcase some of the most varied and rich plant life on Earth.
