10. Read the following paragraphs describing a specific ecosystem. Find the biotic and abiotic factors, and the different populations and communities that form that ecosystem. Tropical rainforests are found in Asia, Africa, South America, Central America, and on many of the Pacific islands. They are often found along the equator. Almost half of the world's tropical rainforests are in the South American country Brazil. What about the climate? Humidity is high and temperature remains constant about 25 C during the whole year. The supply of rainfall is constant everyday, between 200 and 400 cms a year. Tropical rainforests have more species of plants and animals than any other biome. The combination of heat and moisture makes this biome the perfect environment for more than 15 million plants and animals. Many of the plants used in medicine can only be found in tropical rainforests. Rainforest is rich in a great variety of plant species, as trees, lianas, ferns, orchids,… Also, a wide variety of animal species inhabit tropical rain forest: monkeys, bats, squirrels, parrots, birds, snakes, lizards, tapirs, antelope, deer, spiders, insects, termites, bees, butterflies, moths, ants.
