What is meant by an artificial …

A natural ecosystem is the result of interactions between organisms and the environment. For example,
an ocean is classified as a marine ecosystem, which consists of algae, consumers and decomposers. A
cycle occurs in this type of ecosystem that begins with algae converting energy via photosynthesis. After
consumers feed on the algae, energy is transferred between the organisms. Once consumers die in this
system, decomposers turn them into organic matter. This process occurs naturally over a period of time,
whereas in an artificial ecosystem, human intervention is required.
An artificial ecosystem is not self-sustaining, and the ecosystem would perish without human assistance.
For example, a farm is an artificial ecosystem that consists of plants and species outside their natural
habitat. Without humans, this ecosystem could not sustain itself. The plants and animals need the help
of humans to eat and survive. Another major difference between a natural ecosystem and artificial
ecosystem is diversity. Natural ecosystems contain more natural factors and organisms. The
relationships between organisms, each other, and the environment in this ecosystem are more complex
than that of artificial ecosystems.
 A Garden is an example of an artificial ecosystem made by humans while ponds, lakes and forests are natural ones.
