Describe the difference between the nervous system of a filter feeding phyla and the phyla that hunt for food. Discuss the similarities and differences by listing specific organs and structures and their function. describe how these structures make an organism better adapted to a specific feeding method.
The question makes no sense - there are filter feeders in just about every phylum, but (and I may be forgetting a really small phylum) only the sponges are exclusively filter feeders.
