Question

An adult penguin is searching for food for his chick. The number line shows what is at different levels relative to the surface of the water.

A vertical number line from negative 90 to 10. There are 6 labeled points. From bottom to top, the point at negative 86 is labeled, krill: negative 86 meters; the point at negative 59 is labeled, adult penguin: negative 59 meters; the point at negative 32 is labeled, sardine: negative 32 meters; the point at negative 22 is labeled, anchovy: negative 22 meters; the point at 0 is labeled, surface of water: 0 meters; and the point at 5 is labeled, penguin chick: 5 meters.

If the adult penguin dives 27 meters deeper than where he already is, he would be at a depth of $-59-27=-86$ meters. This is the same depth as the krill, so the adult penguin would find krill. Therefore, the answer is $\boxed{\text{(D) Krill}}$.
