The largest reef
in the world is
located where?

Where in the
northern
hemisphere
would you find
a coral reef?
A 200
Off the coast of
Belize or Andros
Island

Where would you
be most likely to
find an atoll?
A 300
Tropical Pacific
ocean around a
sunk volcano

A 400
Explain the
development
of an atoll
A 500
Coral grows up toward
the sun on the sides of
a receding volcano.
The coral continues to
grow up as the
volcano descends

The reef area is
dominated by what
type of fish?

What creatures
contribute to the
structure of the
reef?
B 200
Mollusc shells,
Echinoderms,
Calcareous algae
B 200
What 2 types of
tissues are
necessary for
movement?
B 300
Muscle and
nerve
B 300
Name three
environmental
conditions
necessary for
coral to survive.
B 400
High light intensity
Clear water
Salt water
Warm water ≥ 65 F
B 400
Explain the
development of
a Barrier reef
from a Fringing
Reef.
B 500
The Fringing reef exists close to
shore. Over time, the coral’s
seaward edge grows towards the
open ocean. The Barrier reef is
formed at the edge of the
continental shelf. A lagoon
forms between the reef’s trailing
edge and the land

What are the two
possible destinations
for the food that is
absorbed by the gut?
F 100
Respiration and
growth
F 100
If 1,347 g/hr is absorbed
by the gut of an animal
and 900 g/hr is used in
respiration… then how
many g/hr. goes to
growth?
F 200
447 g/hr.
F 200
• A whale shark has GROWTH
EFFICIENCY of 13%. Is that
good, average or bad? Explain.
F 300
13% would be could good
because the average
absorption efficiency is
10%
F 300
Is an animal ingests
900kg/day and 395
kg/day are
absorbed, what is
the ABSORPTION
EFFICIENCY?
F 400
• 395/900 X 100 = 43.8%
F 400
Solve for growth and absorption
efficiencies.

How would the behavior of
pelagic and benthic organisms
differ based on where they live?
