The semar bag is a carnivorous plant that feeds on insects, caterpillars and frogs. This plant lives as carnivore (carnivorous plant) because it lives in a minimal area of nitrate and phosphate elements. As a carnivore this plant has an insect trap device in the form of a pouch or pot, which is a change in shape from the tipleaf.
To digest these prey plants have protein-soluble enzymes or chemicals in their pockets. Remnants of insects digested, let the ants eat it, so that between ant and semar bag occurs symbiosis mutualisme. This plant is also still doing photosynthesis for the purposes of starch and sugar are the leaves at the base of the stem are flat and green.
Semar bags have many species. These plants live in tropical rain forest areas, ranging from lowlands, medium and high. Most of these plants live in northern Australia, southeastern Asia and southern china. There are 82 species of nepenthes and the most types are found in Kalimantan and Sumatera as many as 64 species.
