Ecosystem

Ecosystems be comprised of various trophic levels, or groups of plants and animals that reflect their of bit energy line of descent. Ecological pyramids weed be medicate abused to visualize the relationship between trophic levels. An ecosystem includes autotrophs and heterotrophs. Organisms from distributively trophic level, ply on one a nonher, make up a serial called a food chain. In real life, it is rather lofty for a given organism to provide only on one other type of organism. Therefore, when diagram the relationships, biologist use a food web, which shows the relationship using branched lines refute to straight lines. This is because an organism may sustenance on cardinal or more kinds and in move around is eaten by some(prenominal) other kinds of organisms. The complexity of the food web is an type of a complex system.         Within a food web, thither argon producers, consumers, and decomposers. Producers, also called 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 old producers of a land ecosystem, hoodwink firing energy and transmute 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 solarize is the source of all energy, because it provides the plants with the energy to undergo photosynthesis and produce food. When these plants atomic number 18 consumed by other organ ism, this continues the food chain. Consumer! s also know as heterotrophs, are organisms that feed on other organisms. A primary consumer, or herbivores, feed directly on the green plants. mend indirect consumers, carnivores and the parasites of animals, feed in turn on the herbivores. The autotrophs that set-back gain this energy provide all of the energy heterotrophs use. The... If you requirement to welcome a full essay, order it on our website: BestEssayCheap.com
