Line graph titled Number of Young Fish Collected at Mangrove Sites in the Egyptian Red Sea During Three Seasons of 2010. The horizontal axis is labeled Season. Its values are Winter, Spring, and Fall. The vertical axis is labeled Number of individual young fish. It ranges from 0 to 40 in increments of 10.
The following 3 lines are shown:
- Common silver-biddy
- Red Sea goatfish
- Milkfish
The Common silver-biddy line:
- Begins at Winter, 35 fish
- Falls sharply to Spring, 17 fish
- Falls gradually to Fall, 10 fish
The Red Sea goatfish line:
- Begins at Winter, 2 fish
- Rises gradually to Spring, 6 fish
- Falls gradually to Fall, 0 fish
The Milkfish line:
- Begins at Winter, 12 fish
- Falls gradually to Spring, 7 fish
- Falls gradually to Fall, 0 fish

Mangroves are trees or bushes that grow on the coastlines of seas and rivers. Areas with mangroves are great places for young fish since they help keep these fish fed and protected while they grow. To study the importance of mangroves to young fish, researchers Mohamed A.Abu El-Regal and Nesreen K. Ibrahim collected and identified young fish from three different mangrove sites in the Egyptian Red Sea. They collected fish in the winter, spring, and autumn of 2010, collecting a total of 269 fish from 21 different species. For some species, more fish were collected in the winter than the other two seasons, for instance: ______
Which choice most effectively uses the data in the graph to complete the example?
Choose 1 answer:
Choose 1 answer:
(Choice A) the common silver-biddy was collected more frequently than the other two species in all three seasons.
A
the common silver-biddy was collected more frequently than the other two species in all three seasons.
(Choice B) in the fall, researchers collected 10 common silver-biddy but collected no milkfish or Red Sea goatfish.
B
in the fall, researchers collected 10 common silver-biddy but collected no milkfish or Red Sea goatfish.
(Choice C) more common silver-biddy and milkfish were collected in the winter than in either of the other two seasons.
C
more common silver-biddy and milkfish were collected in the winter than in either of the other two seasons.
(Choice D) in the spring, researchers collected more Red Sea goatfish than they collected from the other two species.
D
in the spring, researchers collected more Red Sea goatfish than they collected from the other two species.
(Choice C) more common silver-biddy and milkfish were collected in the winter than in either of the other two seasons.
This choice effectively uses the data in the graph by showing that in the winter, both common silver-biddy and milkfish were collected more frequently compared to the other two seasons, demonstrating a pattern of higher collection rates for these species during that season.
