What is an incomplete ecosystem? Explain with the help of a suitable example.
An ecosystem, which is devoid of certain biotic or abiotic factors, is called an incomplete ecosystem. An incomplete ecosystem cannot be a self-sustaining ecosystem. The aquarium is a good example of an incomplete ecosystem.
The aquarium may be having producers and consumers, but it does not have decomposers. Lack of decomposers necessitates frequent cleaning of the aquarium.
