The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.

Option A

Explanation:

Biodiversity is the actual collection of total amounts of flora and fauna present in a particular ecosystem. The river ecosystem consists of the aquatic plants, the aquatic animals like fishes, etc and even the surrounding land plants and animals, who utilize the river water for their living.

The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there. This leads to destruction of the flora and fauna of both water and lands surrounding them. This hampers the biodiversity of the water as well as surrounding land.
