Is it true tropical rain forest cover a small part of the the planet yet they contain more species of plants and animals than all the other biomes?

Yes, it's true that tropical rainforests cover only about 6-7% of the Earth's surface, yet they are incredibly rich in biodiversity. They are home to more species of plants and animals than all other biomes combined, harboring approximately half of the world's known terrestrial species. This high level of biodiversity is attributed to the warm, moist climate and complex ecosystems found in these regions.
