Southeast Asian Rainforest Introduction:

South East Asian Rainforest Location Map
South East Asian Rainforest Location Map
The Southeast Asian Rainforest is the oldest and most biologically diverse rainforest in the world, being 70 million years old. This makes it older than the Amazon and the African Rainforests. With a range of more than 3,100 miles, it is crowded with plants and animals (F, Lydia). The Southeast Asian Rainforest is made up of organisms that can only be found in Southeast Asia, which makes it diverse from other rainforest organisms.

In the south east asian rainforest the biotic factors interact with the biotic factors. The biomes biotic factors like the bengal tiger, and the bengal bamboo both rely on the suns heat to stay warm. The sun is a abiotic factor and gives heat to the biomes biotic factors. Water is another abiotic factor that interacts with the biotic factors in the biome. Water falls from the sky as rain and the biotic factors like the slender loris and silvery gibbon drink the water to survive.

This video shows what it would be like to go through parts of the Southeast Asian Rainforest and a few of the animals that inhabit it. It also shows scenes from the Jungle Book which takes place in part of the Southeast Asian Rainforest. It shows the animals from the movie in there habitats and also consuming food.

Abiotic factors that can be seen in the Southeast Asian Rainforest are the leaf litter and dead trees that are in the soil that is on the ground. These abiotic factors are then decomposed by insects, fungi, and other decomposers. The climate of Southeast Asia is a tropical wet climate in the Köppen climate zone system. The climate is influenced by wind systems which start in the Indian Ocean and the South China Sea. The sun also shines on the upper canopy and below. The rainforest is always very humid, and the temperatures are always high.


Like most tropical rainforests the Southeast Asian Rainforests' biotic factors a very diverse. The animals in this biome range from the great Bengal Tiger to the shy and innocent Slender loris. The Bengal tigers will eat mammals big or small whether it be a Rhinoceros or a Musang. The Rhinoceros is a herbivore so it consumes producers like the fig's of a fig tree and Bengal Bamboo. Musang's are omnivores and will eat ripe fruit like the Durian fruit and will also eat small mammals like the Slender Loris. Then the Slender Loris being a herbivore will eat the leaves of the Tualang Tree.

Paragraph Form:

1)One of the disruptions that effects our ecosytem that we chose to write about was acid rain. Acid rain is a very destructive force that brings much damage to the rainforest's. It has many causes by different factors. To get information on how acid rain effected our biome we asked ourselves questions like what animals would be directly affected by it, and how our biome overall will be affected. We wanted to know what types of acid rain there were, what makes acid rain, and what ways people can stop acid rain to save the rainforest. We got all our acid rain thoughts down then we went and looked up information for our questions we had which helped lead us up to this.
2)Acid rain is is another way to describe the many ways that acid rain falls out of the atmosphere. A better term is acid deposition which has two parts; wet and dry. Wet deposition refers to acidic rain, fog, and snow. As acidic water flows over and through land, it affects many of the plants and animals in that ecosystem. Dry deposition relates to acidic gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition. The wind blows these acidic particles and gases onto buildings, homes, and trees. Dry deposited gases and particles can also be washed from trees and other surfaces by rainstorms. When that happens, the runoff water adds those acids to the acid rain, making the water more acidic than the falling rain alone. ("What is Acid")
3)In general for tropical rainforests' they are effected heavily by acid rain.Because it is mainly caused by industrial processes, automobiles, and power plants, countries that are developed have the most acid rain problems. But, as the undeveloped nations begin to industrialize, acid rain will increase even more. Determining how much the planet is being hurt by acid rain is very difficult because the strength of the effects depend on many things, including how acidic the water is, and the types of fish, trees, and other living things that rely on the water. In a rainforets the effects would be disasterous. Acid rain comes down to the earth in form of rain, snow, hail, fog, frost or dew. Once it reaches the ground, the acidity in the substance can harm and even destroy organism's living in the biome. Acid rain causes leaves on plants to lose all its nutrients, so plants like the Tualang would be hurt by acid rain. This would cause a chain effect for organisms if their food dies, and animals from all parts of the food web would be endangered.

4)Acid Rain kills off the first level of organisms first, which would devastate the food web from the bottom to the top. Many organisms would die if the problem continues to worsen. The cities around the rainforest must reduce the amount of nitrogen oxide and sulfur dioxide that they release into the air. To reduce the amount of these gases that are let into the air, that area around Southeast Asia must find cleaner ways of producing energy. Some ways of doing that are, by using solar and wind energy. These methods create no waste and don’t run out over time. They are unlike fossil fuels that create a lot of waste and break down the ozone layer. Cars must reduce emissions by burning fuels cleaner so fewer acids reach the atmosphere. Planting and growing additional plants and trees would also help take away some of the emissions, and release more oxygen.
5)The Southeast Asian Rainforest is the oldest representative of rainforests in the world, and losing organisms from this rainforest would be a tragedy. Acid rain can be limited and prevented by humans, so it would be sad to lose organisms to a cause that can be prevented. The Southeast Asian Rainforest took millions of years to get to this point, but could be ruined by us in the near future.
