⭕ Natural water bodies are not cleaned while aquarium needs regular cleaning because water in natural river bodies like river or lake keeps moving. It is not still so the impurities are not accumulated whereas in aquarium , water is still so impurities settle down at bottom so it needs regular cleaning. Also decomposers eat the impurities in rivers whereas there are no decomposers in aquarium !

⭕ Decomposers are nature cleaners. They decompose dead and decaying organic matter and convert them into humus. They help to clean the environment !

⭕ If decomposers are eradicated from an ecosystem then no dead and decaying organic matter will be eaten and converted into humus.

⭕ There will be an imbalance in ecosystem !
