Tropical Rainforest

Tropical Rainforest
Climate description:
Usually found 5 degrees south of the equator. It is found in southeast asia, Central Africa and South America. There is no dry season in the tropical rainforest. The time of higher sun and longer days is distinctly driest even though there is no distinct differences between seasons. There are a few cases were this is found not near the equator. The difference of temperature between day and nght is usually larger than the temperature between different seasons. There is a lot of direct sunlight which produces a lot of rain through evaporation. 77 degrees Fahrenheit is the average temperature, never dropping below 64 F(18 C). The average rainfall is over 150 cm, in one month it receives 4 inches of rain. While the tropical rainforest gets a lot of sun the under parts of the rainforest is protected by the coverings of other trees, so many plants have to deal with low amount of sunlight.

Plant Adaptations
Many plants that make up the first layer of the rainforest have to deal with low sunlight. Many ferns, mosses and epiphytes live here, they do well with little sun. Due to the lack of wind, many plants have adapted to different forms of self pollination such as using elaborate flowers to attract birds, bats, or insects to help pollenate In drier, temperate deciduous forests a thick bark helps to limit moisture evaporation from the tree's trunk. Since this is not a concern in the high humidity of tropical rainforests, most trees have a thin, smooth bark. The smoothness of the bark may also make it difficult for other plants to grow on their surface. Larger leaves allow them to collect sunlight for photosynthesis and radiate heat during hot weather. Lianas are climbing woody vines that drape rainforest trees. They adapted to life in the rainforest by having their roots in the ground and climbing high into the tree canopy to reach available sunlight. Many lianas start life in the rainforest canopy and send roots down to the ground.

Animal Adaptations
parrots and toucans eat nuts, and developed big strong beaks
Many rainforest animals use camouflage to 'disappear' in the rainforest.

Stick insects are perfect examples of this.
Some animals are poisonous, and use bright

Colors to warn predators to leave them alone. There are several species of brightly colored poison arrow frogs.

Wings: Larger birds of prey who hunt of amongst forest allow them to weave between trees and hunt for there prey easily (owls, goshwaks)

Body shape is changed to deal with the cool rainforest temperatures the Tasmanian pademelons developed a rounder body shape which retains body heat better.

Symbiotic relationships

Mutualism
Leaf cutter and fungus

Parasitism
The strangler fig envelopes trees

Commensalism
Bromeliads, grow on trees to get extra light.

Competetion
For sunlight between trees, new trees cant grow because older trees have established there spots absorbing sunlight.
