As apex predators, polar bears, walruses, Arctic foxes, and beluga whales are all affected by changes in the Arctic food web as a result of climate change.
Missing a food web diagram that could explain the effect of changes in predator populations.
Passed initial science review - expert science review pending.
Inclusion of a food web diagram would enhance understanding.
Teachers of younger students may wish to introduce the more advanced vocabulary.
