Detailed explanation-4: -The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). Rainfall: The word “rainforest” implies that these are the some of the world’s wettest ecosystems.

Detailed explanation-5: -Hence tropical rain forests are the most species-rich biome on Earth. Because of a high plant diversity, tropical rain forests also contain huge collection of animals including various insects, amphibians, reptiles, mammals and birds.
