Answer to Question 1

B

Answer to Question 2

Meiofauna are small marine organisms that live in the spaces between sediment particles. These organisms, generally only 0.1 to 2 millimeters long, feed primarily on bacteria removed from the surface of sediment particles. Meiofauna include polychaetes, mollusks, arthropods, and nematodes and live in sediment from the intertidal zone to deep-ocean trenches.
