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. The presence of Enhydra lutris in Surge Bay presents what type of factor for the Strongylocentrotus franciscanus population? 
 
a) Density dependent
b) Density independent
c) Competitive exclusion
d) Symbiosis
