Whale Food Chain
A whale food chain is much shorter than the food chain of dolphins.
This is due to the fact that large whales that filter feed with their baleens, take prey from very low levels in the food web.
And advantage of that is that they don't get poisons in their bodies as do the animals up on the top of the web.
Large baleen whales eat animals on the first, second and third level:
Plankton eat dead animals.
Krill eat plankton.
Fish eat krill.
Baleen whales eat mainly krill and plankton, but also eat small fish.
