There are tropical rain forests in South America, Asia, and Africa. It is a very unique biome because the conditions in which it's biotic factors are put in forces them to adapt in interesting ways in order to survive. For example, in the tropical rain forest, less than 2 percent of sunlight actually reaches the ground. Some other abiotic factors that affect the tropical rain forest are excessive rainfall and humid conditions.
The climate of the tropical rain forest is intense. The forest gets about 50 to 260 inches of rain each year, which is more than any other biome. Tropical rain forests are located around the equator, which means they get approximately 11 to 12 hours of sunlight a day. This also means that since this biome gets more direct sunlight than any other, the water on the ground is evaporated making it very humid, and also restarting the water cycle (explaining all the rain). The average temperature in the rain forest ranges from 68 degrees Celsius to 92 degrees Celsius.
