Biology Final Part II

1. Most of the primary production carried out in the open ocean is performed by:

Phytoplankton

Seagrasses

Squidward

Zooxanthallae

2. Zonation in an estuary is made evident by:

Large number of worms in the mud

Presence of different species along different horizontal levels in relation to tides

Tide pools along mud flats

3. Mangroves belong to one of the following groups:

Flowering plants

Green algae

Brown algae

4. Reef building corals grow only in shallow water because:

Salinity varies less in shallow water

Zooxanthallae need light for photosynthesis

Nutrients concentrate in shallow water

5. The infauna of mud flats feed mostly on:

Detritus

Plankton

Filter feeders

6. Fringing and barrier reefs develop:

In waters along estuaries

In the open ocean far from land

Along a coast

7. The most common type of coral reefs around the world:

Barrier

Fringing

Oyster reefs

8. Eutophication is very detrimental to the development of coral sice it increases:

The amount of nutrients in the water, stimulating overgrowth

Temperature of water, since it kills the coral

The salinity of water, since it kills zooxanthallae

9. Most attols are found in theL

Indo-west pacific region

Carribbean

The eastern atlantic

I mispelled caribbeam. damn too lazy to change

10. The expulsion ofzooxanthallae due to unfavorable conditions is called?

Exflagellation

Exudation

Bleaching

Conditioning

11. The sweeper tentacles of corals contain:

Zooxanthallae

Nematocysts

Enzymes

12. Succulents are plants that:

Excrete salts by way of salt glands

Lose water and salts

Accumulate water in their tissues

13. Primary production is very high in coral reefs but low in surrounding waters. One reason for this is that:

Nutrients are efficiently recycled

Turf algae releases nutrients

There is abundant carbon in the reefs

14. Spur and groove formations, or buttresses, appear to be the result of:

Fish grazing

Wind and waves

Accumulation of sand

15. Blood rich in hemglobin is an adaptation to:

Fluctuating salinities

Wide variations in temperature

Low oxygen concentrations

16. Planula is the name given to:

Coral larvae

The coral skeleton

Zooxanthallae

17. The most important organisms that help form coral reefs, other than reef-building corals, are:

Sponges

Corraline algae

Molluscs

18. Reef-building corals are cnidarians that are characterized by

Having both a polyp and medusa stage

Lacking netocysts

Having only a polyp stage

19. Outwelling in estuaries is most important since it:

Maintains high primary production

Provides food and nutrients to other communities

Releases much oxygen

20. Reef corals compete with soft corals for space one competitive advantage of soft corals is their:

Color

Toxic chemicals

Special stingers

21. Practically all of the sediment that accumulates in a coral reef is of what type?

Biogenous

Monogenous

Heterogenous

I don't give a crap

22. Mangrove forests are considered a stage in the ecological succession between marine and terrestrial communities due to the fact that they:

Live mostly above water

Serve as a nesting place for birds`

Accumulate sediment in their roots

23. Zooxanthallae are essential to reef-building corals because the:

Provide the coral with carbon dioxide

Filter out harmful solar raditaion

Help in the deposition of the skeleton

24. The food web in salt marsh communities is characterized by high primary production. Most of this production is made available to other communities in the form of:

Plant tissue eaten by grazers

Detritus

Plant tissue eaten by filter feeders

25. Generally, one important thing between barrier reefs and fringing reefs is that barrier reefs

Develop from attols

Develop farther away from land

Develop in the carribbean

26. Attols actually start as a:

Fringing reef

Barrier reef

Reef flat

27. The epipelagic is divided into two components. The oceanic waters and:

Photic zone

Neritic zone

Pelagic calm

28. Giant clams are very large in size because of their ability to:

Have zooxanthallae

Be parasites when young

Be a deposit feeder

29. The net phytoplankton consists mostly of very small:

Copepods

Diatoms and flagellates

Nanoplankton

Nanoplankton and diatoms

30. Hermatypic corals are those that:

Only live in tropical waters

Are non reef builders

Have zooxanthellae

31. The zonation of plants in marshes is determined mostly by:

Temperature fluctuations

Geographical location

Height of the tide

32. The mesenterial filaments of corals are important because they:

Help deposit the skeleton

Secrete digestive enzymes

Produce mucus

33. Obligate symbionts are those organisms that:

Have a casual relationship with the host

Harm the host

Are found only in association with another species

34. Nanoplankton consists mostly of very small:

Phytoplankton

Copepods

Sea jellies

35. Most zooplankton feed on:

Strictly phytoplnakton

Mostly zooplankton

Mostly nanoplankton and phytoplankton

36. Sources of food and other essential nutrients for corals include all of the following except:

Nutrients released by the zooxanthallae

Calcium carbonate from shells

Zooplankton captured by tentacles

37. Aside from zooxanthallae, what is the other primary producer in a corral reef?

Turf algae

Benthic diatoms

Kelps

38. The goegraphical distribution of mangrove forests is mostly determined by:

Salinity

Type of sediment

Temperature

39. In a typical fringing reef, most of the live coral is found on the:

Reef flat

Reef slope

Reef crest

40. The recruitment of coral reef fishes seems to be the result of one of these phenomena

Species tend to avoid competition

The outcome of competition is based on chance

Species actually choose when to compete and move elsewhere
