The document summarizes the different layers of the rainforest, including the forest floor, understory, canopy, and emergent layer. The forest floor contains fungus, mushrooms, and insects that use mushrooms for shelter. The understory provides humidity that keeps animals warm and is home to boa constrictors, poison dart frogs, and insects. The canopy experiences heavy rain that easily breaks through the leaves, and is inhabited by monkeys and fruit bats. Some emergent layer trees can grow as tall as 200 feet or as tall as skyscrapers, and house monkeys, snakes, and insects, with branches that form a swirling pattern like umbrellas.
