ecological
pyramid
is the picture between trophic
arrangement can be structured based on population density, dry weight, and the
ability to store energy at each trophic. Trophic structure can be arranged in
the order corresponding relationship between eating and being eaten trophic
generally shows a cone or pyramid shape. Ecological pyramid serves to indicate
comparative picture between trophic levels in an ecosystem. At the first level
occupied by manufacturers as the basis of the ecological pyramid, then primary
consumers, secondary, tertiary to the top of the consumer. [1] [2]
When the organisms autotrophs (producers) are eaten by herbivores (consumers I), the energy stored in the producers (plants) passed to the consumer I (pemakannya) and consumer II will get energy from eating consumer I, and so on. Each level of the food chain is called the standard trophies. There are several levels to the extent the trophy following dining chain. [3]
* The level of trophy 1: organism from producer groups (primary producers)
* The level of trophy 2: organisms from the class of herbivores (primary consumers)
* The level of trophy 3: organisms from among carnivores (secondary consumers)
* The level of trophy 3: organisms from among carnivores (consumers predator)
In the food chain, not all energy can be harnessed, but only some of which had migration from one organism to another, because in the process of transformation from one organism to another organism that was part of the energy is released and can not be utilized. For example, green plants as producers occupy the first level trophy only use about 1% of the energy of sunlight that falls on the earth's surface through photosynthesis are converted into organic matter. [3]
When other organisms eat green plants (primary consumers), then only 10% of the energy comes from green plants used by the organism for growth and the rest were relegated in the form of waste heat to the atmosphere. During the state of producers and consumers still form a pyramid, the natural balance of the ecosystem will be maintained.
