This document discusses different climate types and the tropical rainforest ecosystem. It describes warm/tropical climate as located around the equator with high temperatures, humidity, and precipitation. Temperate climate is between the Arctic and tropics with average temperatures of 15C and precipitation of 150L/m3. Polar climate is between polar circles with low temperatures, scarce precipitation, and no humidity. The tropical rainforest has high humidity, large plant variety, and excessive vegetation near the equator in parts of South America, Africa, Asia, and Australia.
