A team of marine biologists observed feeding patterns of several populations in the ocean. The energy pyramid shown, depicts the feeding patterns the marine biologists observed. Which of the choices best describes the energy pyramid

• A. There is less energy available in the producers because their tissues are less dense than those at higher trophic levels

• B. There is more energy available in the second trophic level because less energy is needed for hunting compared to the higher trophic levels

• C. There is more energy available in the tuna because they have greater muscle mass for storing energy than organisms in lower trophic levels have

• D. There is less energy available in the fourth trophic level because of the loss of energy through metabolism in each of the lower trophic levels
