Solution
The correct option is A Aquatic animals excreting in lakes
The causes of water pollution are numerous. Humans are either not aware or they deliberately pollute water bodies without thinking of the consequences.
- Washing clothes using chemical detergents results in their accummulation near the river banks.
- Factory waste like chemicals, sewage, etc., are sometimes dumped into lakes and rivers without proper treatment.
- Chemical fertilizers which are used for enhanced crop production will also pollute water by either seeping into ground water or getting washed away into rivers and other water bodies.
The excreta of aquatic animals in lakes will be decomposed naturally. Hence, these do not pollute water.
