Question
Is an aquarium a complete ecosystem?
✓
Answer
Aquarium is man-made ecosystem and it has its own limitations. The confined space of aquarium cannot have endless supply of inorganic materials for producers. For supporting even a small number of consumers, there is a need for a large number of producers which is not possible in a small space of aquarium. One needs to provides food for the fish in the aquarium and regular cleaning of aquarium is also necessary. This shows that an aquarium is not a complete ecosystem because it is not self-sustainable.
