Tropical Rain Forest

By Catherine Wood

the inpacts of humans

They chopped down the trees that block the sunlight.Therefore increasing temperature.They take minerals,flowers,and other things.To make beverages and medicine.They kill animals in order to get food.LIke if they killed a snake,now more frogs can live and eat more grass and plants.And pretty soon they'll be no more grass and plants.And grass and plants is a main source of oxygen.And when they do this,they throw the food chain and the society totally off. we should be concered about the extetion of animals. the hawk and friut bats are being effected when they cut down tree's. we can donate to a group that help's protect the rain forest, and tell your friends and family members about the program and encourage them to do the same. Private enterprises and charities are a better way to do this than the US applying pressure on Brazil to stop unilaterally.

the tropical rain forest region maps

Tropical rain forest are mostly found in Central Mexico, Africa, South America, and South East Asia

Average Temperature

The temperature rarely gets higher than 93 degrees Fahrenheit, and it rarely gets below 68 degrees Fahrenheit.

Average Rainfall

The Rain forest gets over 100 inches of rain yearly, it normally gets around 50-260 inches.

Average Humidity

Between 77% and 88%of humidity

a producer in a organism that makes ther own food/energy-plants

Also known as the Honey Bee Tree, the tualang grows in the Southeast Asian rainforests of Borneo, Malaysia, Palawan, Sumatra and Thailand. It is an emergent tree that grows to 250 feet tall. The tualang has smooth, slippery bark and enormous buttress roots that grow out to the sides to hold the tree up. Asian rock bees build honey combs in the high branches of the tualang. The combs can reach six feet in diameter and contain tens of thousands of bees.


Like the Panda

Because Every animal can't make there own food so they have to lok for food or hunt for it and Eat the other organism or plant's for energy-animals.

Panda are adapted because they have good teeth to eat the bamboo. And cheetah have the fast reflex’s to catch their prey faster so they can use their energy to catch its prey but then gets the prey and the energy from the prey replaces the energy to catch the prey. A black Mamda uses his heat sense’s to stalk his prey and attack at the right moment to strike and kill his prey with its venom to paralyzed it prey to kill it.

tropical rain forest food chain

consumers: snake= hawk= tiger.

consumer are animals that eats a prey and the animal gets eaten after words and it's like teh flow of energy go's to one organism to another

tropical rain forest energy pyramid

the producers go to the primary consumers and the primary consumer go to the secondary consumer and they go to the tertiary consumers. like the flow of energy to another ecosytem.

The threat to tropical rainforests from climate change may have been exaggerated by environmentalists, according to a new study.

Researchers have shown that the world's tropical forests thrived in the far distant past when temperatures were 3 to 5C warmer than today.

They believe that a wetter, warmer future may actually boost plants and animals living the tropics.The findings, published in the respected journal Science, come from a study of pollen trapped in rocks during a natural period of global warming 56.3million years ago.

The extreme warm spell - called the Paleocene-Eocene Thermal Maximum - saw global temperatures soar by 6C (11F) within a few thousand years.

The cause of the PETM is unknown. However, some scientists believe it was triggered by the release of vast amounts of carbon dioxide from volcanic activity over a few thousand years.

The injection of carbon dioxide into the atmosphere set off a spiral of events that warmed the climate and led to even more greenhouse gas entering the atmosphere, they say.

Researchers at the Smithsonian Tropical Research Institute in Panama examined pollen trapped in rocks in Colombia and Venezuela before, during and after the PETM.

They found that the amount of plant-life in the forests increased rapidly during the warming event with new plant species evolving much more quickly than the older species became extinct.Pollen from the chocolate family and passionflower plant family were found for the first time.The researchers believe the hotter, wetter conditions - and additional carbon dioxide in the atmosphere - boosted plant-life and increased biodiversity.A baby white-faced capuchin rests on a branch with its mother in the tropical rainforest of Manuel Antonio National Park. Researchers believe that a wetter, warmer future may actually boost plants and animals living the tropicsThe findings could shed light on man-made global warming caused by the release of carbon dioxide from burning coal and destroying forests.

Conservative computer models of climate change suggest the world will warm by at least 2C over the next century.

'It is remarkable that there is so much concern about the effects of greenhouse conditions on tropical forests,' said Dr Klaus Winter of the institute.

'However, these horror scenarios probably have some validity if increased temperatures lead to more frequent or more severe drought as some of the current predictions for similar scenarios suggest.'

British forest expert Dr Simon Lewis of Leeds University said warmer, wetter weather could boost rain-forests. However, if climate change led to more droughts, it could be disastrous for regions like the Amazon.

In the last five years, the Amazon has experienced two 'one in a century' droughts, he said.

'The 2005 Amazon drought was widely characterised as an unusual 1-in-100 year event, which caused tree deaths leading to rotting trees releasing over four billion tonnes of carbon dioxide,' he said.

'And now in 2010, another drought has stuck, which initial analyses show is more extensive than 2005, even though it is only five years later.

'These droughts are consistent with model projections showing a die-back of the Amazon, further accelerating climate change in a dangerous loop.

'The new paper is useful, but doesn’t address present-day concerns of drought-impacts that affect the forest itself and the millions of people who live there.'

The speed of modern day man-made climate change was much faster than the global warming of 60million years ago, he added.
