Questions 27

Answers

1
Why should humans care for/ take action against degradation of coral reefs?
all of the above
hold some of the world's greatest biodiversity
removal CO2 from atmosphere
constant sites of tourism which helps economy
2
The open sea can be divided into which of the following vertical zones?
coastal
euphotic
abyssal
a and b
3
Cloudiness that results from nutrient overload is reffered to as...
benthos
marine fog
photic
turbidity
4
Why are Mangrove Forests important ecological systems?
they are not important because of low biodiversity
provide ecological/ economic services
a and c
they are closest to shore so they act as filter
5
Why is it that some organisms found in bathyl zone will migrate to feed on surface?
ther's a higher abundance of food available
both a and c
it is not bathal organisms that migrate, it's euphotic
To ensure they don't use all the food in their zone
6
All of the following are characteristics of low primary productivity EXCEPT?
A and B
low level of nutrients & oligotrophic lake
high levels of O2
clear water & low population of phytoplankton
7
List the layers of the deep lakes (top--> bottom)
littoral->profundal->benthic->limnetic
lettoral->limnetic->profundal->benthic
littoral->profundal->limnetic->benthic
benthic->profundal->limnetic-.littoral
8
Benthos consists of all of the following organisms EXCEPT...
oysters
fish
worms
clams
9
The area of shoreline between low and high tides is called...
coastal zone
intertidal zone
abyssal zone
open sea
10
Saltwater covers about what percentage of the earth's surface?
52%
83%
71%
27%
11
What makes life in coastal wetlands harsh for the organisms that inhabit them?
there tend to be more predators in these areas
Must be able to withstand constant changes
the areas are too large too inhabit
there;s too much competition amongst organisms
12
Plankton can be divided into which of the following?
phytoplankton
all of the above
zooplankton
ultraplankton
13
Coral reefs are the marine equivalent of what terrestrial biome?
tropical rainforest
desert
tundra
savanna
14
Why is it that most marine life populates the top layer of the ocean?
top layer isn't the most populated
top layer is where all marine animals mate
top is where most resources are found
top layer is largest in size
15
Estuaries are where what bodies of water met?
rivers and sea
none of the above
streams and lakes
rivers and lakes
16
Why is the open sea the largest contributor of NPP
both a and b
largest biodiversity
some upwellings bring nutrients from bottom to the surface
covers up so much of Earth's surface
17
How does surface water become runoff?
if rain doesn't evaporate or sink into the ground
if snow doesn't evaporte or sink into the ground
all of the above
none of the above
18
What is the largest estuary in the US?
Pacific Ocean
Chesapeake Bay
Hudson Bay
Indian River
19
Why had commercial harvests populations declined?
deforestation
overfishing
A & C
pollution
20
The global ocean can be divided into which of the following?
All of the above
Atlantic
Arctic
Pacific
21
What is the difference between eutrophic and oligotrophic lakes?
A and C
eutrophic is murky & oligotrophic is clear
eutrophic has many nutrients&oligotrophic has few nutrients
eutrophic has few nutrients&oligotrophic has many nutrients
22
How do streams shape land they pass?
they flow downhill and create friction with land they pass
they do not shape land
by degrading the land
none of the above
23
What kind of feedback loop is runoff of nutrients into lakes? why?
negative feedback loop;algae decrease
negative feedback loop;algae increase
positive feedback loop;algae increase
positive feedback loop;algae decrease
24
Which of the following is a way in which coral reefs provide ecological/economic services?
support important fishing and tourism industries
help moderate atmospheric temperatures by removing CO2
all of the above
act as barriers for erosion of land near the shore
25
Which open sea vertical zone contains phytoplankton and high O₂ levels?
none of the above
abyssal
euphotic
bathyl
26
Eutrophication occurs__while cultural eutrophication occurs __.
B and C
because there are little nutrient;naturally
naturally;because of humans
because of humans;naturally
27
What would happen to aquatic food chain if plankton were removed?
food chain would prosper
the food chain would quickly recover
aquatic food chain would fall apart
no change
