Location: The tropical rainforests contain the greatest diversity of species of all biomes on earth. They are found around the equator, between 23.5 degrees N latitude and 23.5 degrees S latitude.Climate: Temperatures in tropical rainforests remain between 68 and 77 degrees Fahrenheit all year long. Winter is absent in these forests. Most tropical rainforests receive 100 inches of rain per year.Soil: Because the temperature is warm and the air moist, decomposition happens at a very fast rate in tropical rainforests. High levels of rainfall often lead to leaching of nutrients from the soil, creating soils that are nutrient poor.Plants: Trees in the tropical rainforests grow between 82 and 115 feet tall and are typically broad-leafed trees. Other plants include ferns, vines, mosses, palms and orchids.Animals: Dense growing trees create a thick canopy layer in tropical rainforests that keep the sun from penetrating to the lower layers of the forest. This means that most animals that live here must be adapted to living in the trees. A variety of birds, bats, monkeys, snakes and other animals can be found in tropical rainforests.Threats: The biggest threat to tropical rainforests is unsustainable forestry practices. Other threats include road construction, clearing land for agriculture and other development activities and climate change.
