Ok thanks for answering.
An ecosystem which is created by human beings and did not exist naturally is\xa0artificial ecosystem.Example- Forests, ponds are natural ecosystem and gardens, crop fields are artificial ecosystem.
Artificial ecosystem means… ecosystem which is created by human beings…Like ,garden, ponds , forests .

Thank you for answering my question.
An ecosystem created by humans which can\’t exist naturally. Aquarium and ponds are its examples
An artificial ecosystem is man-made, it is not natural. Example- Parks, Aquarium

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. Acycle occurs in this type of ecosystem that begins with algae converting energy via photosynthesis. Afterconsumers feed on the algae, energy is transferred between the organisms. Once consumers die in thissystem, 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 naturalhabitat. Without humans, this ecosystem could not sustain itself. The plants and animals need the helpof humans to eat and survive. Another major difference between a natural ecosystem and artificialecosystem is diversity. Natural ecosystems contain more natural factors and organisms. Therelationships between organisms, each other, and the environment in this ecosystem are more complexthan that of artificial ecosystems.\xa0A Garden is an\xa0example of an artificial ecosystem\xa0made by humans while ponds, lakes\xa0and forests are natural ones.

Example:- pond,dam etc
The ecosystem which is formed or manufactured by human beings is known as artificial ecosystem.
Digrable and biodegraeble
