What happens to sand dollars when the water becomes too acidic?
My stupid global studies teacher assigned this project to us and I was wondering if you could answer this question.
- He's not stupid, he wants his students to THINK and be able to research a basic question. I found it in less than 2 seconds using google.20
- Yes, I CAN answer the question. The point is, can you? Now get to work and stop waiting for things to be handed to you.20
- How is it that your teacher is earning money teaching you yet you refer to him/her as stupid? As far as answering this question, your “stupid” teacher has the knowledge needed to answer it. Ask them.10
- Sand Dollars, like clams, crabs, sea urchins and other marine creatures (in salt water reefs, for example), produce protective outer shells (or "exoskeletons") made of calcium carbonate. They need these shells to live. Without them, they will die. Calcium Carbonate dissolves in very high acidity, so if the ocean water is acidic enough it can destroy the shells and thereby kill the sea creatures. But even slightly elevated acidity may prevent the Sand Dollar and the others from producing their protective shells, thereby decreasing their chances of survival.00
