O Competition Mutualism O Parasitism PredationIf a parasite’s life cycle involves multiple hosts, what might control the population dynamics of the parasite? Briefly discuss. What is mutualism? Look up some examples of relationships that have been identified as mutualisms and examine them critically. Are they in fact mutualistic?Mistletoe is a plant that attaches to trees or shrubs. Special mistletoe structures called haustorium penetrate the branches of the and shrubs. The mistletoe is then able to absorb water and nutrients from the plant, leading to illness and sometimes death of the host plant.* 1 and 2 O Commensalism ghschool O Symbiosis O Mutualism O Parasitism O Competition Sea otters, Enhydra lutris, are predators of sea urchins, Strongylocentrotus franciscanus. Sea urchins, in turn, feed on kelp. A study was conducted to tietermine the effect that Enhydra lutris has on kelp biodiversity.

Which of the following is consistent with this finding? O Parasites do not generally kill their hosts; thus they can feed on the same host throughout the host's normal life span and do not have competition from decomposers. O Parasites almost always predigest their hosts' tissues and, therefore, spend less energy and require fewer structural adaptations. O Parasites, unlike predators, feed on almost all the tissues of their host. O Parasites generally kill their host and can feed for a very long time because they are much smaller than their host.Parasitism is one of the most widespread lifestyles ever to evolve.
