Water

Approximately 80-90% living body composed of water. Water is used as a solvent in the cytoplasm, to maintain osmotic pressure cell, and prevents the cell from the drought.
Indonesia is located on the equator and between the two continents, has enough rainfall high, averaging 200-225 cm / year. High rainfall and uneven, the sun throughout the year, and temperatures average 27 ° C caused Indonesia has the diversity of flora and fauna is high. The lower the rainfall, the lower the diversity variety too. In the area of East Nusa Tenggara, the rainfall is only 100 cm / year, many pastures and bush savanna known as the diversity of the relatively lower.


In the western part of Indonesia, the high rainfall many tropical rain forests found that a relatively high diversity.
On the surface of a large rock can be found differences in diversity due to differences in moisture or water content. On the stone that is always damp or wet, moss or plants found nail growth, while in the dry parts of plants not found.
Two examples above show that water is a very important role in determining the diversity of life.
