What is a bears food chain?

Bears eats all types of food including man,vegetables etc

well a grizzly bear eats small fish like trout so their food chain would be similar to

Bear > Salmon > smaller fish > tiny shrimp > algae

but a polar bear is a bit different

bear > seals > penguins > squid > shrimp > plankton

although all of the animals (including bears) eat other animals/plants but in a food chain like theese you just choose one. if you want a more in-depth one with all of the bears etc. food sources just google it or something..
