Answer 1

Sea urchins and clams are more likely to be affected by the increasing acidity of the ocean. These organisms have calcium carbonate shells or exoskeletons, which can be negatively impacted by lower pH levels, making it harder for them to grow and maintain their structures. Fish and seaweed may be affected by changes in their environment due to ocean acidification, but the direct impact on their physical structures is less severe compared to that on clams and sea urchins.
