Describe and diagram the various zones and provinces in the ocean. What adaptations to these variable conditions are

seen in the biota that inhabit these regions? What will be an ideal response?


Concepts to Consider: Neritic province overlies the continental shelves and is a highly
productive zone; the photic region of the neritic province is particularly productive and rich
in species; oceanic province is the open ocean area portion of the ocean and most is aphotic;
neritic organisms depend on marine snow as a base for the food chain; the benthic
environment includes sandy areas as well as the productive kelp forests and coral reefs; the
intertidal zone is between the high and low tide levels; intertidal organisms are characterized
by adaptations to variations in wave action and to possible desiccation.
