Where are North west coast animals food chains?

It's not entirely clear what you mean by "North west coast animals food chains." Do you mean:

* The food chains of animals living on the northwest coast of a specific continent? (e.g., the Pacific Northwest coast of North America, the northwest coast of Australia, etc.)

* The food chains of animals that live in the northwest portion of a specific ocean? (e.g., the Northwest Atlantic Ocean, the Northwest Pacific Ocean, etc.)
