Concept:Salinity of brackish water changes with rainfall and evaporation.
Explanation:Brackish water contains a mixture of fresh water and salt water.
Rainfall adds fresh water, which dilutes the salt concentration.
So salinity decreases after rainfall and at the end of the rain.
In the dry season, evaporation removes water but leaves salts behind.
This increases salt concentration in the remaining water.
Therefore, salinity of a brackish habitat rises during the dry season.
Answer:D. increases during the dry season
