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

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.
