The aquatic ecosystem of Coringa mangrove region would be less salty than the bay. Do you agree to this why? Why not? (AS1)

Yes, the aquatic ecosystem of Coringa mangrove region would be less salty than the bay. This is because Coringa ecosystem is formed at the junction of two rivers Gowthami and Congo. The Congo River brings fresh water to the ecosystem and the Gowthami River brings saline water to the ecosystem. Thus, the salinity of the water in this ecosystem is reduced due to the presence of fresh water.
