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
Endangered animals must be saved to protect the balance of the ecosystem. When one species goes extinct, it greatly impacts the food chain.Full Answer >
In addition to overtaking and replacing native plants in an ecosystem, kudzu can alter the nitrogen balance of the soil and release dangerous ozone into the atmosphere. The vines also release volatile organic compounds into the air that can exacerbate smog when combined with other particulate pollutants. Kudzu's root systems can also drain an ecosystem of available water, leaving the few plants that survive its presence parched and dying.Full Answer >
Living and nonliving things interact with each other by forming an ecosystem, where living things can obtain nutrients and energy from nonliving things through chemical processes. The nonliving things in an environment are known as abiotic factors, while living things are known as biotic factors.Full Answer >
Abiotic factors of a pond are all elements that are in or that affect the ecosystem of a pond other than the living, or biotic, factors. Abiotic factors vary by pond and include a wide range of components such as temperature, stratification, density, oxygen and carbon dioxide levels, salinity, and calcium and nitrogen levels. Even the length of the day and the climate are considered abiotic factors of a pond.Full Answer >
