sea urchins

clams

Answer 1

Sea urchins and clams are more likely to be affected by increasing ocean acidity. Both of these organisms have calcium carbonate shells or structures, which can be negatively impacted by more acidic conditions. The increased acidity can hinder their ability to build and maintain these structures, potentially leading to decreased populations.

Fish and seaweed tend to be less directly impacted by acidity changes, though the overall health of marine ecosystems can still affect them indirectly.

So, the best responses regarding those more directly affected would be **sea urchins** and **clams**.
