Question

Explain why a large animal like a humpback whale can feed on such small animals as krill or other plankton and yet still have the energy and mass available to produce such a large biomass.

Answer 1

whales rely on their baleen to feed on relatively small aquatic organisms. Their diet primarily consists on fish, krill, and plankton. Toothed whales are better equipped to grab larger, individual prey animals like fish, squid, and other invertebrates. Some species in the Odontoceti suborder have been known to even eat seabirds and smaller marine mammals
