Artificial ecosystem are :
- The ecosystems that are created and maintained by man.
- The ecosystem made by the addition of energy and planned manipulation with a natural balance.
- Corp lands, orchards, gardens, aquariums, greenhouses etc., are examples for artificial ecosystems.
- All of these
The Correct Option is D
Approach Solution - 1
An ecosystem is a functional unit of nature, where living organisms interact among themselves and also with the surrounding physical environment. Ecosystem varies greatly in size from a small pond to a large forest or a sea. Forest, grassland and desert are some examples of terrestrial ecosystems; pond, lake, wetland, river and estuary are some examples of aquatic ecosystems. Crop fields and an aquarium may also be considered as man-made ecosystems or artificial ecosystems. These are the ecosystems that are maintained by the man with certain manipulation.
So, the correct option is (D): All of these.
Approach Solution -2
Artificial ecosystems encompass ecosystems that are created and maintained by humans (option A), ecosystems where energy and natural balance are manipulated and planned (option B), and examples such as crop lands, orchards, gardens, aquariums, greenhouses, etc. (option C). Therefore, all the given statements describe aspects of artificial ecosystems.
So, the correct option is (D): All of these.

Concepts Used:
Ecosystem
An ecosystem is a structural and functional unit of ecology where the living organisms come in to interact with each other and the surrounding environment.
Structure of the Ecosystem:
The structure of an ecosystem is distinguished by the organization of both biotic and abiotic components. This involves the distribution of energy in our environment. It also comprises the climatic conditions prevailing in that particular environment.
There are two main components of the structure of an ecosystem, namely:
- Biotic Components
- Abiotic Components
The biotic and abiotic components are interconnected in an ecosystem. It is an open system where the energy and components can flow through the boundaries.
