Transcribed Image Text: Sea otters, Enhydra lutris, are predators of sea urchins, Strongylocentrotus
franciscanus. Sea urchins, in turn, feed on kelp. A study was conducted to
determine the effect that Enhydra lutris has on kelp biodiversity. To do so, three
bays that have had sea otter populations for varying amounts of time were
assessed. Two different types of kelp were studied: a perennial kelp, Laminaria
groenlandia, and other annual kelps. The results are shown in the graph below.

Removal of Enhydra lutris leads to the collapse of Stronylocentrotus franciscanus Strongylocentrotus franciscanus prefers Laminaria groenlandia to annual kelps. OEnhydra lutris is an important component of the kelp community (7.W+#) Áisu
