2 Module Overview For the past 8,000 years, the ice cores of Antarctica and Greenland indicate that Earthâs climate has been unusually stable. Yet global climate has changed several times in Earthâs geological history, sometimes at a relatively abrupt rate, as shown by the Greenland ice core data. In the module, Temperature Over Time, you compared temperature patterns and trends over different time scales and regions.
It feeds on a wide variety of creatures. Smaller seals probably eat mostly krill, but also squid and fish. Larger leopard seals probably switch from krill to more substantial prey, including king, adelie, rockhopper, gentoo, emperor, and chinstrap penguins, and less frequently, other seals, such as crabeater seal.
Of course, the menu in the ocean is a lot larger than what your food chain shows! Individual animals can eat many other types of plants and animals, not just one.For example, a seal likes to eat other fish like salmon, and seals in turn can be eaten by larger animals such as orca whales. On a third triangle, draw a picture of each plant or animal. 2  To complete your ocean food pyramid, tape the tab on your first triangle to the underside of your third triangle.
