Ecosystem

Ecosystems be comprised of various trophic levels, or groups of plants and animals that reflect their of importee energy line of descent. Ecological pyramids canful be medicine abused to visualize the relationship between trophic levels. An ecosystem includes autotrophs and heterotrophs. Organisms from all(prenominal) trophic level, ply on one another, make up a serial called a food chain. In genuine life, it is rather lofty for a given organism to head for the hills only on one other type of organism. Therefore, when schematization the relationships, biologist use a food web, which shows the relationship using branched lines refute to straight lines. This is because an organism may range on cardinal or more kinds and in change form is eaten by some(prenominal) other kinds of organisms. The complexity of the food web is an model of a complex system.         Within a food web, thither argon producers, consumers, and decomposers. Producers, also calle d autotrophs, make their own food and can restrain themselves. Once energy enters an ecosystem, usually from photosynthesis, it is slowly released as metabolous processes proceed. Green plants, the main(a) producers of a land ecosystem, amaze firing energy and transform it into food energy. This group consists of autotrophs that convert solar energy into chemical energy; they do not expect to obtain their energy from other living organisms.

Thus, the sunshine is the source of all energy, because it provides the plants with the energy to undergo photosynthesis and produce food. When these plants be consumed by other orga nism, this continues the food chain. Consume! rs also know as heterotrophs, are organisms that feed on other organisms. A primary consumer, or herbivores, feed directly on the green plants. piece of music indirect consumers, carnivores and the parasites of animals, feed in turn on the herbivores. The autotrophs that low gain this energy provide all of the energy heterotrophs use. The... If you indirect request to welcome a full essay, order it on our website: OrderCustomPaper.com
