Tritrophic Interaction

 Tritropic interaction is an interaction that includes three organisms. First, the plant or producer of food resources is the main of interaction. The second is a consumer of producers. The consumer is mainly herbivores that disruption in other organisms, especially on plants. The last are natural enemies. Commonly, the natural enemies always come when the plants that attacked by some herbivores. Actually in this interaction have two types of natural enemies (Parasitoid and Predator). More people has known about predator function or activity. Example, paryer manthis and ladybug. The parasitoids are an organism that has function as a predator doing. We know about that function when we look at the circulation of the ecosystem. 

The animal in the ecosystem always death. The examples are mouse farm death because an eagle ate the mouse. Just like that, an herbivore death by predators and parasitoids. The predators killed the herbivores often diggest directly. The parasitoids often killed the herbivores more softly.

The picture illustrates the Thritropic interaction. According to the above explanation, we can conclude that plant is maize, the herbivore is aphids, and the predator is a ladybug. The plants have two protection. First is direct protection, like grow some part of the body that function against herbivores. The second is indirect protection, like in the picture. Ladybug was deriving on maize and diggest the aphids. Chemicals materials were out from plants that invite some natural enemies (ladybug as predator). It was out from plants because plants get induced by herbivores.
