Throw chunks of food on the ground, the first animal to reach it is ants. This is true in most of the mainland where there are ants. In terms of the number of individuals and biomass (weight), fleet ants dominate nearly all terrestrial habitats in the world. Day or night, the army ants vigorously explore the mainland, so they can find food before the other animals find it.
With the ecological dominance, it was natural that the ants can be found everywhere. From tall buildings to lush forests, from the coast to the area subalpin. Ants are also present in the soil up to a tall tree, in the desert to tundra. In fact, today you are likely not far from worker ants roaming around you.
Ant dominance is also reflected in the number of insect biomass. In the composition of the biomass of insects in the world, at least one-third consists of ants. The amount is quite large considering the total number of ant species is less than 2% of the total number of insect species. The number of ant species in the world estimated at 20,000, and 12,000 of them have been known to science. In Indonesia alone there are about 1,500 species have been described, but it is estimated there are about 500 species remain to be discovered.
The identification of ant species in Indonesia is difficult because there are at least taxonomic study of ants here. Even so, do not need a complex research to find out how many species of ants roaming around our house. When a simple observation, it can be seen at least 3 species of ants around the house. Several different species more can be found on the home page.
When you observe the ants in the community around you, do not be surprised if you find various living species in a relatively narrow area. Most ants are small, with a length of less than 5 mm. With this small body, the resources needed to survive relatively small anyway. Thus more ant population can survive in a small area compared to the animals that are larger in size.
Moreover, an ant colony has a system of division of labor in the fleet workers. In this system, each member of a colony of ants running certain jobs according to the needs of the colony at that time. Jobs colonies are foraging, nest building, keeping the enemy, care for chicks, producing eggs, or reproduction. With the division of labor, the work of the colony performed effectively and efficiently thereby increasing resilience and survival of the colony.
