Interаctiоns between freshwаter оrgаnisms Identify the fоllowing relationships: (for example, competition, mutualism, etc.) A. The relationship between branchiobdellid worms and crayfish. Branchiobdellid worms live on crayfish and feed on small organisms living on the crayfish shell and gills. This cleaning by branchiobdellids increases crayfish growth and survival. B. The relationship between unionid mussels and fish. Juvenile unionid mussels temporarily attach to the gills of fish, allowing the mussels to disperse to new habitats. The mussels do not harm the fish. C. The relationship between phytoplankton and snails. Phytoplankton shades out benthic algae that is the food source for snails, hindering snail growth. The presence of snails does not impact phytoplankton.   You are studying a species of pond snail that is infected with a parasitic fluke. You notice that the infected snails are spending more time out in the open than the uninfected ones. D. What do you suspect is going on? Is this behavior likely to benefit the parasite or the host? E. You want to design a study to comprehensively test the effects of this parasite on the snail host. In addition to altering behavior, what are two other ways that parasites often impact their hosts?
