Solved by a verified expert:BIO 112: Porifera and Cnidarian LabVirtual LabPhylum Porifera: McGraw Hill LabData -Name of OrganismType of FeederJournal Questions1. Describe each of the four types of feeders identified in this activity. Explain how various invertebrates haveadapted to feeding in their environment.2. Why are filter feeders usually stationary organisms?3. Early scientists classified sponges as plants. Based on observations of the sponge’s feeding system, why doyou think scientists now classify sponges as animals?4. Jellyfish cannot swim rapidly, yet they are efficient predators. How are they adapted to predatory lifedespite their lack of speed?5. Why are scavengers usually found in the lower part of the coral reef habitat?6. How do internal parasites keep from being washed out of their host’s bodies in the body fluids or wastes?7. How do the methods for obtaining food change as an organism’s complexity increases?8.
