Rainforests: Earth's Oldest Ecosystems

10 Questions

Rainforests are the oldest living ecosystems on Earth. Some have survived for 70 million years. These warm and wet forests can be found in every continent except Antarctica. In a rainforest, rain falls almost every day. There is a constant buzz from millions of chirping bugs. Animals and plants found nowhere else on Earth call the rainforest home. Among these animals are the smallest frogs and largest spiders. So many animals and plants live in the rainforests, that no one has been able to count them all. Rainforests have four layers that each have unique plant and animal life. The top layer of a rainforest is made of tall trees. Some grow to be more than 200 feet tall. This layer is called the emergent layer. Trees in the emergent layer get a lot of sun. Many birds and monkeys live in these tall trees. The middle layer of a rainforest includes the canopy and understory layers. This middle layer is made of small trees with strong branches. The toucan and two-toed sloth live here. The bottom layer is the forest floor. It is wet and muddy. Leaves and small bushes cover the forest floor and giant anteaters roam this layer. Many things we use come from the rainforest. Trees are used to make furniture and build homes. Rubber comes from the sap of the rubber tree. We use the sap to make rubber balls, boots, tires, and other things. We use the seeds of the fruit from cocoa trees to make chocolate. Some rainforest plants are used to make medicine.
