Q: What is the correct sequence of zones in a pond ecosystem from bottom to top?
  • A. Hypolimnion-Thermocline-Epilimnion
  • B. Littoral-Thermocline-Epilimnion
  • C. Epilimnion-Hypolimnion-Thermocline
  • D. Hypolimnion-Thermocline-Littoral
Correct Answer: Option A - The correct sequence of zones in a pond ecosystem from bottom to top is : Hypolimnion-Thermocline-Epilimnion. Hypolimnion is the deepest layer of a pond or lake and is typically the coldest part because it is furthest from the sun's warming rays. Thermocline is the middle layer that acts as a buffer between the upper and lower layers. It's where the temperature changes most rapidly with depth. Epilimnion is the topmost layer and is well-lit and warmer due to direct sunlight. Littoral zone is the shallow area near the shore.
