An artificial ecosystem meets all the criteria of a natural ecosystem but is made and controlled by humans. It is created to mimic a natural ecosystem but often is less complex and with a very low genetic diversity. Orchards, farmlands, a garden and man-made reservoirs are some examples of artificial ecosystems.Know More
A natural ecosystem consists of a diverse species of plants and animals that significantly interact with the nonliving things that are also present in the system. It is naturally sustainable and does not require the intervention of humans to survive. A forest and a pond are both examples of a natural ecosystem. An artificial ecosystem, however, cannot thrive productively without human supervision.
Humans need to tend to each component of an artificial ecosystem to make it a sustainable environment. A paddy field requires fertilizers and a consistent supply of water in order to grow crops. When the crops are harvested, it leaves the farm an open system that depends on external sources in order for new plants and organic matter to develop and thrive. A garden needs to be tended by pulling out weeds and eliminating parasites through chemical or organic fertilizers. Small rodents, insects and birds can also survive in the garden and provide biodiversity, but humans drive away most of these animals to maintain the equilibrium of the garden.Learn more about Environmental Science
Protists serve numerous purposes in the ecosystem including producing between 70 and 80 percent of the world's oxygen, being a main food source for aquatic animals and a major decomposing agent of dead material. Protists can measure up to 300 feet long, as in the case of the giant kelp of the kelp forests in the Pacific Ocean.Full Answer >
There are two types of deserts: temperate, or cold, and subtropical, or hot, which gives deserts more than one type of ecosystem. There are similarities as both get less than 10 inches of rain a year, and the air is generally dry in both types of biomes. The lack of water in either type of desert makes them harsh for people or creatures living there.Full Answer >
A freshwater ecosystem is a type of aquatic ecosystem with a low salt concentration. It includes lakes, ponds, springs, rivers, streams and wetlands. It may be divided into two categories: the lentic or still water ecosystem and the iotic or the flowing water ecosystem.Full Answer >
The decomposers in an underwater ecosystem are animal-like organisms called protists, fungi and bacteria. Referred to as saprotrophs, these organisms decompose dead matter from higher-level plants and animals, facilitating the re-entry of nutrients into the ecosystem in the form of raw nutrients and carbon dioxide.Full Answer >
