In this graph of marine iguana foraging start times, what pattern emerges between when iguanas forage in the intertidal zone versus the subtidal zone?

A) Marine iguanas switch every few weeks between foraging in the intertidal zone throughout the day, and only foraging in the subtidal zone around midday.
B) Marine iguanas forage equally between the intertidal and subtidal zone at any time of day.
C) Marine iguanas initially forage primarily in the intertidal zone but switch to foraging in the subtidal zone as temperatures get cooler.
D) Marine iguanas switch between foraging in the intertidal zone at night, and the subtidal zone during the middle of the day.
