Study Notes

Tropical Rainforest Geographical Areas

Tropical Rainforests are located around the equator in Central America, Africa, and Indo-Malaysia
Amazon River basin located in Central America
Zaire basin and a small area in West Africa, as well as eastern Madagascar are located in Africa
West coast of India, Assam, Southeast Asia, New Guinea, and Queensland, Australia are located in Indo-Malaysia

Tropical Rainforest Layers

Emergent Layer: 100 to 240 feet tall trees with umbrella shaped canopies that grow above the forest.
Upper Canopy: 60 to 130 foot trees. Sunlight is available at the top, but significantly reduced below.
Understory: 60 feet tall trees consisting of trunks of canopy trees, shrubs, plants, and small trees.
Forest Floor: Usually completely shaded, except where a canopy tree has fallen. Very little light restricts plant growth.

Tropical Rainforest Landforms

Mountains: The highest Tropical Rainforest mountain is Pica da Neblina, located in the Amazon Rainforest.
Karst Landscapes: Tehuacan stone snakes (tecuates) found in North America, Mexico, Puebla, along several streets in Tehuacán, also in El Riego Park
Rivers: The Amazon River in South America is the largest river by water volume and the second-longest river system in the world.

Tropical Rainforest Climate

Rainfall: 2,000 to 10,000 millimeters (79 to 394 inches) of rain per year.
Temperature: Mean temperatures range between 68 and 84 °F. Temperatures do not fall below 64 °F.

Tropical Rainforest Abiotic & Biotic Factors

Abiotic: Soil composition, humidity, temperature, sunlight.
Biotic:
- Buttress Roots: Large roots help support large trees.
- Ferns: Epiphytes that live on tree branches high in the canopy. They obtain nutrients from the air and water, not from soil.
- Maiden's Blush: Leaves with pointy tips to allow water to quickly run off and prevent damage.

Tropical Rainforest Food Web

Producers: Green plants utilize sunlight, water, and soil for photosynthesis.
Herbivores: Agouti and tapirs feed on these plants.
Secondary Consumers: Boa constrictors consume herbivores for energy.
High-trophic-level Carnivores: Jaguars, crocodiles, and birds of prey consume carnivores and omnivores.
Decomposers and Scavengers: Bacteria, fungi, and toucans break down dead organisms and recycle nutrients into the ecosystem.

Tropical Rainforest Natural Resources

Renewable Resources: Avocado, guava, trees (used for building & medicine), plants, animals, passion fruits, oils from trees.
Nonrenewable Resources: Minerals like gold and copper, cattle, hydroelectric energy.

Human Impact on Tropical Rainforests

Consuming Food: Avocado and guava are consumed.
Building Materials: Trees used to construct houses and other buildings.
Oil Extraction: Oil used for frying.
Gold Mining: Used for fashion and other purposes.
