How do kelp beds in the northeastern U.S. differ from those of the northwestern U.S.? What is the dominant non-human predator in each habitat?
What will be an ideal response?
In the northeastern U.S. kelp beds are dominated by thick, closely-spaced Laminaria kelps. These kelp beds give rise to very close packing that selects animals that do not swim but, rather, crawl around the kelp bed. The dominant predators in these beds are lobsters. On the west coast, kelp beds are dominated by Macrocystis kelp, which does not grow as densely with the result that the animals here can swim freely amongst the kelp. The dominant predator in northwestern U.S. kelp forests is the sea otter.
