Question

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?



(1 point)

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.

Energy decreases as it is transferred from krill to birds, since krill are producers and birds are primary consumers.

When fish consume the carnivorous plankton, about 90 percent of the plankton's energy is transferred to the fish.

Answer 1

Answer: "When leopard seals consume birds, about 10 percent of the birds' energy is transferred to the leopard seals."

Explanation: As energy moves up trophic levels most is lost (respiration, heat, waste); typically only about 10% is passed to the next level, so statement 2 is correct.
