Lab 9: Ocean Life
Deliverable #1:
1.
If a marine species is impacting the biodiversity of a coral reef in a negative way, that
species is considered (highlight the correct choice):
a. An Ecosystem Engineer
b. An Invasive Species
c. A Keystone Species
2.
If a keystone species is removed from an ecosystem, the ecosystem experiences a(n)
(highlight the correct choice):
a. Loss of biodiversity
b. Increase of biodiversity
3.
What is an example of an ecosystem engineer? (highlight the correct choice)
a. Walruses
b. Sea Otters
c. Whales
d. Lionfish
Deliverable #2:
1.
Please paste your pie chart below number 1. This pie chart displays the sighting
frequency of fish at the Flower Garden Banks. This data was collected by NOAA divers
and volunteers throughout a long term study of diversity. Sighting frequency is how
often a species was observed. Pie chart 14 points.
2.
Based on these percentages, what fish was observed the most? (highlight the correct
choice):
a.) Bluehead
b.) Spanish Hogfish
c.) Brown Chromis
d.) Bicolor Damselfish
e.) Sharpnose Puffer
3.
What fish species were sighted the least? (highlight the correct choice):
a.) Atlantic Creole Fish
b.) Spanish Hogfish
c.) Great Barracuda
d.) Blue Tang
e.) Black Durgon
4.
What is the range of the sighting frequencies of these 10 species? (highlight the correct
choice):
a.) ≈ 50%
b.) ≈ 25%
c.) ≈ 35%
d.) ≈ 10%
e.) ≈ 80%
5.
If we were presenting this graph, we would have to make a broad statement about
these species. What could you (broadly) say about the sighting frequencies of these fish
species? *With more research, we would be able to be more specific about these
distributions. (highlight the correct choice):Hint: Look at the size of each pie segment
a.) The sighting frequencies are about the same for these species.
●
Blue Chromis (75%) & Black Durgon (75%)
b.) The sighting frequencies are really different for these species.
●
Bluehead (97.92%) & The Great Barracuda (72.92%)
