Answer:
Viruses are neither prokaryotes nor eukaryotes because they lack all of the characteristics of living things except for the ability to reproduce. They are considered parasitic because they cannot live or replicate without a living host. Viruses consist of genetic material (either DNA or RNA), a protein coat, and sometimes a lipid envelope surrounding the protein coat. They have no function except to reproduce.
Bottom feeders are aquatic animals that feed on the bottom of a body of a water. Crayfish is the bottom feeder. It is not active swimmer, it feed on stationary or slow pray, so it does not have such a streamlined body necessary to reduce drag during swimming. Its mouth is located on the underside of their heads and that way mouth is closer to the bottom where their food is.
