The Tropical Rainforest
The tropical rainforest is my absolute favorite biome. It is very extraordinary because of its animals, climate, and plants. This region is full of year-round warmth. There is an average of fifty to two-hundred sixty inches of rainfall per year. The temperature in rainforests rarely gets hotter than ninety- three degrees fahrenheit or colder than sixty- eight degrees fahrenheit. The average humidity is about seventy-seven or eighty percent, and there is often more than one-hundred inches of rain per year. Almost all rain forests lie near the equator. Rainforests now cover less than 6% of Earth’s land surface. Scientists estimate that more than half of all the world’s plant and animal species live in tropical rain forests.
A tropical rain forest has more kinds of trees than any other area in the world. About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, and is used as an anesthetic and to relax muscles during surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with lymphocytic leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. The majority of the trees have smooth, thin bark because there is no need to protect the them from water loss and freezing temperatures. It also makes it difficult for plant parasites to get a hold on the trunks. The bark of different species is so similar that it is difficult to identify a tree by its bark. Many trees can only be identified by their flowers.
Many species of animal life can be found in the rain forest. Insects make up the largest single group of animals that live in tropical forests. They include brightly colored butterflies, mosquitoes, camouflaged stick insects, and huge colonies of ants. There may be 40 to 100 different species in 2.5 acres of tropical rainforest. There are many unique animals that roam the rainforests. These include extraordinary animals such as the pygmy elephant, sloths, amazon butterfly, amazon stingray, anaconda, spider monkeys, and so much more!
