The rainforest is one of the oldest and most diverse ecosystem in the world! It has a variety of biotic elements including many producers, omnivores, fierce predators, scavengers, and decomposers. It’s a good habitat for all living things because of the fact they produce 40 percent of the earth’s oxygen! Rainforests are mainly found in the northern part of South America, central Africa and southern Asia. They have an average temperature of 21 to 30 degrees celsius, and the climate is very humid. This is because rainforests are always near the equator. The area of the biggest rainforest, which is the Amazon is 5.5 million square kilometers, so it provides a habitat for over 10 million species of biotic elements!
