Detailed explanation-1: -Tropical rainforests support the greatest diversity of living organisms on Earth. Although they cover less than 2 percent of Earth’s surface, rainforests house more than 50 percent of all plants and animals found on land.

Detailed explanation-2: -Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.

Detailed explanation-3: -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-4: -Rainforests receive the most rain of all of the biomes in a year! A typical year sees 2, 000 to 10, 000 millimeters (79 to 394 inches) of rain per year.

Detailed explanation-5: -Days and nights are almost equal in length throughout the year. These regions get plenty of rainfall. Tropical rainforests get continuous warmth and rain and hence this region has a wide variety of plants and animals dwelling there.
