1. Mollusca include:
a. crabs, shrimp and spiders.
b. sponges – filter feeders.
c. bivalves, squid, octopus, gastropods (things with shells or large cavities).
d. coral, jellyfish.
2. Echinodermata include:
a. sea stars, urchins and sea cucumbers (all with spiny skin).
b. single celled organisms: foraminifera, radiolarians, copepods.
c. bivalves, squid, octopus, gastropods (things with shells or large cavities).
d. squid, octopus, nautilus, cuttlefish.
3. Porifera include:
a. crabs, shrimp and spiders.
b. sponges – filter feeders.
c. bivalves, squid, octopus, gastropods (things with shells or large cavities).
d. squid, octopus, nautilus, cuttlefish.
4.
Annelida include:
a. crabs, shrimp and spiders.
b. worms.
c. squid, octopus, nautilus, cuttlefish.
d. sponges – filter feeders.
5. Arthropoda include:
a. crabs, shrimp and spiders.
b. sponges – filter feeders.
c. worms.
d. coral, jellyfish.
6.
Protozoa include:
d. coral, jellyfish.
b. foraminifera, radiolarians, copepods.
c. worms.
c. bivalves, squid, octopus, gastropods (things with shells or large cavities).
7. Coelenterates include:
a. crabs, shrimp and spiders.
b. sponges – filter feeders.
c. squid, octopus, cuttlefish, nautilus.
d. anemones, coral, jellyfish.
8. Deep-ocean floor communities live in under high pressure conditions around hydrothermal vents.
These warm to hot water vents on the seafloor often host local communities that include an abundance of
unusual life forms - including giant tube worms, giant clams, giant mussels, and crabs. These larger
organisms derive their food from a microbial community in the water and sediments around the vents that
make up the base of the local food chain. The life in this zone derives the energy they need to live from:
a. photosynthesis.
b. chemosynthesis.
c. consumers.
d. decomposers.
9. Coral reefs only occur and thrive in:
a. tropical settings.
b. shallow water conditions.
c. warm and clear water conditions.
d. all of the above.
10. The largest accumulation of biogenous sediments associated with coral reefs found in the world today are associated with:
a. the Great Barrier Reef of Australia.
b. the Caribbean inlands reef.
c. The Amazon rain forest.
d. The Amazon delta.
