[Campbell Biology P.1227] What is the primary ecological benefit of seasonal turnover in lake... | Practice Question

What is the primary ecological benefit of seasonal turnover in lakes, as described in the text?

  • A: It primarily helps in rapid ice formation during winter.
  • B: It sends oxygenated water to the bottom and brings nutrient-rich water to the surface.
  • C: It maintains a constant temperature throughout the lake year-round.
  • D: It prevents the growth of aquatic plants in deep waters.

Explanation

The text explicitly states: 'This turnover... sends oxygenated water from a lake's surface to the bottom and brings nutrient-rich water from the bottom to the surface in both spring and autumn.' This process is crucial for the health of the lake ecosystem.
