Why are some shellfish (ocean animals, like oysters, that have shells) in danger of going extinct? None of the above. Fewer shar
ks is disrupting the ecosystem for these organisms. C The ocean is getting too salty Carbon in the atmosphere is making the ocean more acidic and they can't build their shells. E Warm water is making less algae (food for shellfish)
The question is formatted a bit weird. Shellfish are in danger of being extinct because carbon makes the oceanmore corrosive and acidic, making it harder for them to build shells.
