About This Quiz
2.
What's your name?
We’ll put your name on your report, certificate, and leaderboard.
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
Submit
3.
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
Submit
4.
Mangroves belong to one of the following groups:
Flowering plants
Green algae
Brown algae
Submit
5.
The infauna of mud flats feed mostly on:
Detritus
Plankton
Filter feeders
Submit
6.
The most common type of coral reefs around the world:
Barrier
Fringing
Oyster reefs
Submit
7.
Fringing and barrier reefs develop:
In waters along estuaries
In the open ocean far from land
Along a coast
Submit
8.
The expulsion ofzooxanthallae due to unfavorable conditions is called?
Exflagellation
Exudation
Bleaching
Conditioning
Submit
9.
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
Submit
10.
Most attols are found in theL
Indo-west pacific region
Carribbean
The eastern atlantic
I mispelled caribbeam. damn too lazy to change
Submit
11.
The sweeper tentacles of corals contain:
Zooxanthallae
Nematocysts
Enzymes
Submit
12.
Succulents are plants that:
Excrete salts by way of salt glands
Lose water and salts
Accumulate water in their tissues
Submit
13.
Spur and groove formations, or buttresses, appear to be the result of:
Fish grazing
Wind and waves
Accumulation of sand
Submit
14.
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
Submit
15.
Blood rich in hemglobin is an adaptation to:
Fluctuating salinities
Wide variations in temperature
Low oxygen concentrations
Submit
16.
Planula is the name given to:
Coral larvae
The coral skeleton
Zooxanthallae
Submit
17.
The most important organisms that help form coral reefs, other than reef-building corals, are:
Sponges
Corraline algae
Molluscs
Submit
18.
Reef-building corals are cnidarians that are characterized by
Having both a polyp and medusa stage
Lacking netocysts
Having only a polyp stage
Submit
19.
Reef corals compete with soft corals for space one competitive advantage of soft corals is their:
Color
Toxic chemicals
Special stingers
Submit
20.
Outwelling in estuaries is most important since it:
Maintains high primary production
Provides food and nutrients to other communities
Releases much oxygen
Submit
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
Submit
22.
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
Submit
23.
Attols actually start as a:
Fringing reef
Barrier reef
Reef flat
Submit
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
Submit
25.
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
Submit
26.
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
Submit
27.
The epipelagic is divided into two components. The oceanic waters and:
Photic zone
Neritic zone
Pelagic calm
Submit
28.
Giant clams are very large in size because of their ability to:
Have zooxanthallae
Be parasites when young
Be a deposit feeder
Submit
29.
The mesenterial filaments of corals are important because they:
Help deposit the skeleton
Secrete digestive enzymes
Produce mucus
Submit
30.
The net phytoplankton consists mostly of very small:
Copepods
Diatoms and flagellates
Nanoplankton
Nanoplankton and diatoms
Submit
31.
The zonation of plants in marshes is determined mostly by:
Temperature fluctuations
Geographical location
Height of the tide
Submit
32.
Hermatypic corals are those that:
Only live in tropical waters
Are non reef builders
Have zooxanthellae
Submit
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
Submit
34.
Nanoplankton consists mostly of very small:
Phytoplankton
Copepods
Sea jellies
Submit
35.
Most zooplankton feed on:
Strictly phytoplnakton
Mostly zooplankton
Mostly nanoplankton and phytoplankton
Submit
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
Submit
37.
Aside from zooxanthallae, what is the other primary producer in a corral reef?
Turf algae
Benthic diatoms
Kelps
Submit
38.
The goegraphical distribution of mangrove forests is mostly determined by:
Salinity
Type of sediment
Temperature
Submit
39.
In a typical fringing reef, most of the live coral is found on the:
Reef flat
Reef slope
Reef crest
Submit
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
