What is a rainforest? • Woodland characterized by lush vegetation, comparatively high temperature, and rainfall throughout the year. • The world’s most biologically diverse ecosystem. • Account for less than 7% of the land surface on earth, but contain more than 50% of its plant and animal species. • Emergent Tree – the tallest trees which enjoy unfettered sunlight. • Canopy Layer – absorbs as much as 90% of the sunlight, darkening the lower regions. • Understory – receives little sunlight, therefore boasts cooler temperature and higher humidity. • Forest Floor – home to many of the rainforest’s insects, reptiles, and amphibians. • Most plants found in the rainforest are unique to that biome. • Many of these plants are eaten by the indigenous people and/or used for medicine. • Millions of plant species exist in the rainforest. • In 15 sq km (6 sp mi) of rain forest, as many as 100 different mammal species may be found. • Most rainforest animals are nocturnal, sleeping during the heat of the day. • Almost 90% of the rainforest animal species are insects, and of these, most are beetles. • Some estimate that as many as 30 million insect species may live in the rainforest. • Indigenous, or native, people have lived in the rainforest for many thousands of years. • Much of their food, medicines, and clothing come from the rainforest. • Besides hunting, gathering wild fruits and nuts and fishing, they also plant small gardens.
