c.

Pollution in marine ecosystems causes a decrease in the formation of algal blooms.

d.

Addition of warm water has no effect on marine ecosystems.

Verified Answer :

Answer is b. Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic.

Burning of fossil fuels release carbon dioxide and other harmful gases in the atmosphere. Carbon dioxide gets dissolves in the ocean to form carbonic acid.  Due to formation carbonic acid, the pH of ocean water changes slightly. The average pH of ocean water was 8.2 slightly basic. Now it 8.1, it means there is 25 % increase in acidity of ocean water.
