Tropical+Rain+Forest+Period+2

** Forest **


**Facts/characteristics of the Biome:**
 * **covers 2% of earths surfaces**
 * **2,000 trees are cut down every minute in the rainforests**
 * **tempuratures rarely go below 60 and over 90**
 * **over 1/4 of the worlds medicain is originated from rainforest**
 * **there are four layers to a rainforest**
 * **Emergent layer- Tall trees**
 * **Canopy layer- denser trees**
 * **Understory- very little sunlight (2-5%)**
 * **Forest floor- less then 2% of sunlight**

**Location of the Biome**:
 * near the earths equator the largest tropical rain forest are in South America, Africa, and Southeast Asia **

**Consumers/Animals living in the biome** :

primary Consumers: small mammals, salmon, insects, deer, elk, and birds
**Producers/Plants living in the biome:** **In Tropical Rain Forest there are many different types of plants. There are hundreds of different types of trees and all of these trees make up four different levles. First there are //__Emergent Level__// which are spaced very far away from each other and grow anywhere from 100-240 feet tall. The two main type of trees that make the Emergent Layer are the Kapok tree and the Brazil Nut Tree. The Next level is the //__Canopy.__//The canopy is the home to the most animals. In this layer the trees are ususally much closer to each other than they were in the Emergent Level. The Canopy gets less sunlight and weather than the Emergent Trees did beacuse they are protected by the taller trees in the upper level. The canopy is mostly made up of trees of the proteacea** **family. The third level is called the Under Story. The understory has less light than the other layers of the forest, getting only about 15 percent of what filters to the canopy. The understory has less vegitation unless it is by a river or an area of deforestation.**


 * Dominant (keystone) species in the biome: zam tree, agouti, jaguar **

**Average Temperature Range for the biome:** **The temperature is not usually higher than 93 degrees or lower than 68 degrees.**


 * Annual Precipiation for the biome: **
 * Tropical Rain forests recieve 50-260 inches of rain per year. **
