A. a grazer
B. a decomposer
C. a filter feeder
D. a chunk feeder

Answer 1

The correct answer is C. A filter feeder

Explanation:

In biology, a filter feeder is a type of organisms, usually animals, that feeds from the particles and the suspended matter found in water usually because they have body structures that act as a filter, for example, baleen whales are filter feeder and they use baleens to get krill from the water. Example of filter feeders includes bivalves, sponges, but also birds such as flamingos. This implies clams are classified as filter feeders because these are bivalves and also because these have specific structures that in this case are gills to filter food particles that are used as food which occurs in filter feeders.
