What type of region has the most biodiversity?
A Temperate rainforest
B Arctic desert
C Tropical rainforest
Thanks to their ample sunlight and moisture, tropical rainforests contain far higher numbers of species than other terrestrial biomes. They are estimated to support millions of species, including some we don’t even know about! The Amazon rainforest is home to more than 40,000 plant species, 1,000 bird species, 3,000 types of fish, 400 species of mammals, and about 2.5 million different insects.
The correct answer is Tropical rainforest.
