What is the Tropical RainforestBiome?

!

Tropical rainforest is earths most complex biome

! 50% of Earths biodiversity

! Abundant rainfall and year round warm temperatures

! Between 28 degrees N/S of the equator

!

Average annual rainfall no less than 66 inches

! Among most threatened ecosystems

Types of Tropical RainForests

! Lowland equatorial evergreen rain forest: receive high rainfall,occur in a belt around the equator. Found in Amazon Basin, CongoBasin, Indonesia and New Guinea

! Moist deciduous and semi-evergreen seasonal forests: high overall

rainfall with warm wet summer and cooler dry winter. Some of thetrees drop their leaves during dry season. Found in S America, CAmerica, W Africa and Indochina

! Montane Rain forests: aka cloud forests are found in cooler climatemountain areas between 1500-3300m in the mountain range

!

Flooded forests: Forests with permanent water accumulationex. Lower floodplain forest, previous floodplain and seasonally

waterlogged swamp forest

Tropical Rainforest Climate

!

Very high precipitation, up to 250 cmper year

! Very humid and wet environment

! Equatorial location results in moistair and high temperatures

! Temperature is rarely higher than 93degrees F and rarely lower than 68

degrees F

! Year- round warm temperatures

!

Understory of tropical rainforestcooler because it receives less

sunlight

Plant life of Tropical Rainforest

! Rainforests have 170,000 of theworlds 250,000 known plantspecies.

! A typical four-square-mile patch ofrainforestcontains as manyas1,500 flowering plants, 750speciesof trees

! Plants must adapt to the extremeamount of precipitation that occur

in this biome! Emergent Layer-tallest trees, as

much as 200 feet above the forestfloor. Sunlight is plentiful

! Canopy Layer-the primary layer ofthe forest and houses a largeanimal life

! Understory Layer-Little sunshinereaches this area, but there is alarge concentration of insectshere.

! Forest Floor-It's very dark soalmost no plants grow in this area.

A mot of decomposition occurs inthis layer

Cacao Plant- Grows below altitudes of

1,000 area that Needs about 4 inches of rain

per month lowland rainforests of Amazon

River basins

Used in making chocolate

Heliconia- colorful plant has 40 different

species with paddle-shapedleaves

part of the banana family Found in the tropics including

southern Mexico, Central andSouth America and the WestIndies

Animal life in the TropicalRainforest

! An estimated 50% of Earths biodiversity is found in TropicalRainforests

! Estimates range from 3 million to 50 million species that inhabit theTropical Rainforest

!

A typical four-square-mile patch of rainforest contains 400 species ofbirds and 150 species of butterflies.

! Animals in this biome must adapt to be very competitive because of thehundreds of others they are competing against for resources

Anaconda- large, non-venomous

snake found in tropicalSouth America

one of the largestsnakes in the world

Poison Dart Frog-These frogs are considered one ofEarth's most toxic species, some

have enough poison to kill 20,000mice. They have a range of brightcolors like yellows, oranges, reds,

greens, blues

Proboscis Monkey-Male proboscis monkeys

use their fleshy,pendulous noses to

attract mates. Proboscismonkeys are endemic to

the jungles of Borneo

Human ImpactMillions and Millions of acres of TropicalRainforest are cleared every year for the

benefit of humans.

An area of a rainforest the size of a footballfield is being destroyed each second.

the two main reasons for this forest clearingis to create land available for agricultural useand to harvest trees in the logging industry

This deforestation results in massive habitatloss for millions of species and soildegradation

Experts estimates that we are losing 137plant, animal and insect species everyday due

to rainforest deforestation, or 50,000 speciesa year

As the rainforest species disappear, so domany possible cures for life-threateningdiseases.

Fun Facts

!

Rainforests are the oldest ecosystems onearth. Some rainforests in Southeast Asiahave been around for at least 100 millionyears, when dinosaurs roamed the earth.

!

Giant bamboo plants can grow up to 9inches a day.

! The trees of a tropical rainforest are sodensely packed that rain falling on the

canopy can take as long as 10 minutes toreach the ground

! Over 25% of natural medicines have beendiscovered in rainforests.

! Global oxygen is 28% from therainforests.
