The food chain for toothed whales is pretty much the same as for dolphins, since olphins are a kind of toothed whale.
look like this:
Plankton eats the bodies of
animals in the ocean.
Krill - small, shrimplike animals -
eat plankton Squid and small fish eat krill.
squid and fish eat small squid and fish. Toothed whales eat the fish and squid, and they also
take crustacians and octopus. The
largest toothed whales which are killer Killer
eat fish and some of them eat small marine mammals and sometimes even
sharks and dolphins.Their diet varies between groups.
the smallest of prey creatures is exposed to even low level toxins from
pollution of the water, it moves up the food chain and becomes
concentrated in the tissues of the larger predators like marine
mammals. This is called "food chain
Planktonic organisms and nektonic
animals, (small creatures like
krill), both range over great expanses. Both carry heavy metals,
pesticides, sometimes even radiation and disease-causing organisms
through all of the oceans on earth. More and more marine mammals are
being poisoned by contamination of our oceans.
Baleen Whales don't have the some problem with "food chain
This is due to the fact that the large baleen whales that filter food
baleens, take prey from very low levels in the food web.
of that is that they don't geta lot of poisons built up in their bodies
as do the
animals up on the top of the web.
eat animals on the first, second and third level:
Plankton eat dead animals.
Krill eat plankton.
Fish eat krill.
eat mainly krill and plankton, but also eat small fish.
