Question 1

Correct Answer:

Verified

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.
