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

Answers

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.

The True statement about the effect of pollution on marine ecosystem is : Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic ( B )

Fossil fuels

When we Burn fossil fuels carbon dioxide and other harmful gases are released into the atmosphere.The Carbon dioxide gases gets dissolves in the ocean to form carbonic acid. The formation of carbonic acid leads to a change in the pH level of the ocean.

Hence we can conclude that The True statement about the effect of pollution on marine ecosystem is : Burning fossil fuels causes a decrease in the pH of ocean water making it more acidic ( B )
