What type of ecosystem covers most of the islands of southeast asia?

The type of ecosystem that covers much of South east Asia is the Rainforest Ecosystem. This ecosystem is characterized by heavy rainfall all year round (up to 4000 mm in some regions). The Temperature does not fluctuate much but remains in the range of 27-33 degrees Celsius annually.
Rain forest ecosystems have deep red soils known as latosols. Species are very diverse; both plants and animals. The trees here can reach up to 40 metres tall for the emergent layer. Trees are tall and have buttress roots for support. The leaves of plants have drip tips to allow water to run off quickly.

In some developing nations the percentage of the animal protein from fish in the diet can be as high as 25 percent.  about 85% of fish caught is used for human consumption.  the remainder is converted into fishmeal and fish oil.
