B. Temperature • 1. The temperature in a rain forest rarely gets higher than 93 °F or drops below 68 °F.
C. Rainfall • An average of 50 to 260 inches of rain falls yearly. • Rainfall is often more than 100 inches a year.
Layers of the Rainforest • Emergent • Upper canopy, most animal life found here • Understory, or lower canopy, constant shade • Forest floor, constant shade
D. Tropical Rainforest Facts • There may be 40 to 100 different species of trees in one hectare (2.47 acres) of tropical rainforest. • More than 20 percent of the world oxygen is produced in the Amazon Rainforest. • More than half of the world's estimated 10 million species of plants, animals and insects live in the tropical rainforests
Interesting Facts • 1500 different kinds of flowering plants • 125 species of mammals • 400 species of birds • 100 reptiles • 60 amphibians • countless insects • 150 species of butterflies • **Only 1% of these species has ever been studied**
Animals • Fauna: Animal life is highly diverse. • Most animal species of any other biome. • Common characteristics found among mammals and birds • bright colors • sharp patterns • loud vocalizations • diets heavy on fruits.

F. Plants • Less than 1 percent of the light that strikes the top of the forest penetrates to the forest floor. • At least 80% of the developed world's diet originated in the tropical rainforest. • 1. avocados, coconuts, figs, oranges, lemons, grapefruit, bananas, guavas, pineapples, mangos and tomatoes; vegetables including corn, potatoes, rice, winter squash and yams; spices like black pepper, cayenne, chocolate, cinnamon, cloves, ginger, sugar cane, tumeric, coffee and vanilla and nuts including Brazil nuts and cashews 2.

Problems Facing the Rainforest • The rainforests of the world are disappearing at a rate of 80 acres per minute due to deforestation. • Farming and logging are the main reason for deforestation. • Ranching also causes destruction of the rainforests. Ranchers clear large areas of rainforest to become pastures for their cattle. • Trees from the rainforest are used for building houses, making furniture, and providing pulp for paper products, such as newspapers and magazines. • Rainforest that was chopped down can grow back over time, but they will never have the same variety of plants and animals they once did.
Problems • Photos of destruction caused by logging, mining, drilling, road building and farming. • http://www.leslietaylor.net/gallery/destruction/destruction.htm
Temperate Rainforest • This is a small biome in terms of area covered. • The main stretch of this habitat is along the northwestern coast of North America from northern California though southern Alaska. • There are also small areas in southern Chile, New Zealand, Australia and a few other places around the world, most of which don't show up on the scale of the map to the right. • In general, such forests form were relatively warm offshore waters affect inland climates.
