Not all adults feed at a high trophic level. whale sharks (50 ft) are the largest fish and feed on plankton and small fish, while great white sharks (20 ft) are the largest carnivorous fish and feed on sea lions, seals and large fish. blue whales (100 ft) are the largest whale and feed primarily on plankton and krill, while the sperm whale (45 ft) is the largest carnivorous whale feeding on fish and very large squid.
(a) how does the location of each animal's position in relation to the producers contribute to their size? be sure to look at the food chain and the amount of energy that is being transferred between the levels.
(b) why do you suppose the plankton feeders are able to attain such large sizes compared to the carnivores?
