Using the image below of a marine food web, answer the following question: Which of the following correctly describes how the amount of energy changes as it flows through trophic levels?
Energy increases as it is transferred from squid to leopard seals, since leopard seals are more
massive than squid.
When leopard seals consume birds, about 10 percent of the birds' energy is transferred to the
leopard seals.
When fish consume the carnivorous plankton, about 90 percent of the plankton's energy is
transferred to the fish.
Energy decreases as it is transferred from krill to birds, since krill are producers and birds are
primary consumers.
