We do not clean ponds or lakes, but an aquarium needs to be cleaned. Why?

Answers (1)

A pond or lake is a natural ecosystem. These are self-sustaining and complete. All the organisms of the food chain are available. If any organism dies, there are decomposers to decompose their bodies into simpler substances.

An artificial ecosystem is a human-made system of plants, animals, and people living in an area together with their surroundings. These are not self-sustainable.

An aquarium is an artificial and incomplete ecosystem. The abiotic components are not supplied naturally. It may not have all the biotic components in it. If a fish dies in an aquarium in the absence of a decomposer, it will lie there like a rotten body, polluting the water of the aquarium. Thus, an aquarium needs regular cleaning and maintenance.
