This can best be seen by showing a food string. An example of a food chain would look like the following: algae  krill  codfish  leopard cachet  killer whale. Food is a crucial element to excerption within an ecosystem as it provides energy which aids in life processes, such as breathing, moving, maintaining organs and reproducing. While food is necessitate to survive, it is obtained primarily from biotic organisms while water and oxygen are obtained from the abiotic environment. While all organisms depend on one another within ecosystems, each has its own position of affect on the environment.





Balance within an ecosystem occurs through a close descent between two species. This relationship called symbiosis is categorized into trey main categories; mutualism, commensalism and parasitism. Commensalism usually occurs between a species that is either endangered to predation or with an inefficient means of locomotion, and another species with a relatively effective system of defense. In a parasitic relationship, the host species is always exploited to some degree, although often in such a way that its health is impaired only slowly. This allows the parasite to exploit its host over a lifelong period. Many parasites only spend a portion of their lives...If you indigence to get a full essay, order it on our website: Orderessay
