Scientists classify clams as consumers. Which observation about clams provides the strongest evidence for this classification?

• Young clams are able to move from place to place.

• Clams gain energy and nutrients by filtering particles from the water.

• Clams use calcium compounds to make a hard shell.

• Clams live on the ocean floor, and sometimes survive without sunlight.
