Feven's Water Ecology

Feven, like earth, has organisms which must coexist in many environments among different communities. Since 65% of the planet is covered by water, and much of that is ocean, there is a large marine ecosystem that is comprised of different types of organisms. At the beginning of the food chain are the producers, those organisms that produce their own food. Consumers then feed on the producers, and larger consumers, in turn, feed on smaller consumers, and finally, when the organism dies, decomposers break down the remains. An ecological pyramid is used to represent the energy relationships among these organisms. In general, approximately ten percent of the energy at one level of the pyramid can be used by organisms at the next level.

Water plants, such as the Liligish are abundant in the ocean because they are able to manufacture energy within their cells through ultraviolet light, infrared heat, and different gases in the atmosphere and water. Thus, these plants reproduce quite rapidly utilizing the different energy sources in their environment.

Primary consumers such as the Sehorsefly, feeds on the Liligish and Caloria to obtain energy. About 90% of the energy is used immediately, and 10% is stored in the tissues of the Sehorsefly.

Secondary consumers, such as the Preyfish then feed on the Sehorsefly so that it may receive energy to survive. Again, only about 10% of this energy is stored in the tissues of the Preyfish.

Finally, when the organism dies, their remains do not build up because decomposers, such as bacteria, then begin to break down the non-living organism.

This process of the marine ecosystem only occurs in the shallow waters of less than 100 meters. On Feven, deep-water ecosystems do not exist, because producers cannot survive at depths over 100 meters. If there is a change in the food chain, the whole ecosystem is then affected. Thus, there must some type of equilibrium within the ecosystem to ensure the survivability of different organisms.
