neritic zone
the region between
the continental shelf
and the surface
of the water
most productive zone
Coral Reefs
• Reef- a natural structure built on a
continental shelf.
• Coral reefs are mainly found in warm,
tropical waters.
• 1/3 of all ocean fish live on or depend on
coral reefs.
• The ecology of a coral reef is a unique and
fragile system.

reef
(coral reef)
the top layer of
a coral reef
a natural structure
built on a continental
shelf from the shells
or skeletons
of small sea animals
is the only part that
contains living
organisms

continental
shelf
the shallow
border that
surrounds the
continents
Coral Reefs (continued)
• Because of the algaes
need for sunlight
coral reefs cannot
grow below a certain
depth.
• Water Pollution is a
major cause of coral
reef damage.
• Chemicals make
water cloudy and
reduce amount of
light.
Estuaries
• Estuary-a region of water in which a freshwater
source, usually the mouth of a river, meets salt
water from the ocean.
• Estuaries are partly enclosed but are still subject
to the rise and fall of ocean tides.
• Many marine organisms lay their eggs in the
calm, warmer waters of estuaries.
• Although estuaries are not as productive as coral
reefs they are much more productive than the
open ocean.

estuary
a region of water
where a freshwater
source meets salt
water from the
ocean
often ringed by
salt marshes
Neritic Zone Productivity
• Waters in Neritic Zones tend to be high in
mineral nutrients.
• Tides play a role in Neritic ecosystems.
• The most important factor is that sunlight
can reach the Benthic Zone of the
continental shelf.
