Tropical Rainforest

By: Justin Sanders

Rainforest in summer, fall, winter and spring

The climate of a tropical rainforest is very hot and wet. The average temperatures of a tropical rainforest are about 80 degrees F all year round with an exception of cool nights. The temperature of the rainforest has never dropped below 64 degrees F. It rains about 160-400 inches each year. In a downpour, only one- third of the rain that falls hits the forest floor.

Temperature and precipitation in the rainforest

Animals found in the tropical rainforest and thier adaptations

Poison dart frogs- bright colors, to warn preditors of its poison

Parrots- strong beaks, to crack open nuts

The Boa Constrictor- Camouflage to suprise its prey

Plants found in the Tropical rainforest and their adaptatations

Bromeliads- grow on trees and catch rainwater.

Mangroves- Wide spreading stilt roots that support the tree in the mud and trap nutritious organic matter.

Epiphytes- Grow on branches of trees to catch sunlight

Soil conditions in the Tropical Rainforest

Most tropical rainforest soils relatively poor in nutrients. Millions of years of weathering and torrential rains have washed most of the nutrients out of the soil. More recent volcanic soils, however, can be very fertile. Tropical rain forest soils contain less organic matter than temperate forests and most of the available nutrients are found in the living plant and animal material. Nutrients in the soil are often in forms that are not accessible by plants.

Constant warmth and moisture promote rapid decay of organic matter. When a tree dies in the rainforest, living organisms quickly absorb the nutrients before they have a chance to be washed away. When tropical forests are cut and burned, heavy rains can quickly wash the released nutrients away, leaving the soil even more impoverished.

Comparison of where nutrients are found

Tropical Rainforest- 52% in Vegetation, 48% in Soil

Temperate Deciduous Forest- 31% in Vegetation 69% in Soil
