Yellow Perch Population Shift in East River
What most likely caused the Walleye to move to a different river?
A) There is a lack of food in the East river which caused the Walleye to move to a different area.
B) The Walleye are no longer able to catch the Yellow Perch and need to move to a different area.
C) There is climate change which has caused the resources to decline in the East river.
D) There is pollution in the East river that the Yellow Perch are adapted to but the Walleye are not.
Answer:
D
Explanation:
The likely reason for the Walleye population to move from the East river to a different river is due to the pollution in the East river. Unlike the Yellow Perch, the Walleye are not adapted to the pollution levels in the East river, making it necessary for them to find a different habitat with cleaner water. This shift highlights the importance of protecting natural habitats and addressing pollution to ensure the survival of various species of fish.
The data provided suggests that the Walleye population has moved from the East river to a new river, and the most likely cause for this migration is the pollution in the East river. Despite having a large population of Yellow Perch, which the Walleye feeds on, the pollution levels in the East river have likely reached a point where the Walleye can no longer thrive in that environment.
Pollution can have detrimental effects on aquatic ecosystems, affecting the water quality and availability of food sources for fish species like the Walleye. In this case, the pollution may have exceeded the tolerance levels of the Walleye, prompting them to seek out a new, cleaner environment in order to survive and thrive.
It is important for environmental conservation efforts to address pollution in water bodies like rivers and lakes to prevent further harm to aquatic life. By reducing pollution and improving water quality, habitats can be preserved and species like the Walleye can continue to exist in their natural environments.
