Answer

Explanation:

Step1: Analyze energy flow in the pyramid

In an energy pyramid, energy is transferred from lower to higher levels. If the secondary consumer (a middle - level consumer) population decreases:

  • Higher - level consumers (tertiary consumers) that depend on the secondary consumer for energy will have less available food. So, the higher levels in the pyramid will receive less energy.
  • Lower - level consumers (primary consumers) that were preyed upon by the secondary consumer will face less predation.

Step2: Eliminate incorrect options

  • Option “The higher levels in the pyramid will receive more energy” is incorrect because there are fewer secondary consumers (energy sources for higher levels).
  • Option “The higher levels in the pyramid will receive no energy at all” is incorrect. There may be other secondary consumers or alternative energy paths (though not as prominent in a simple analysis).
  • Option “The lower levels in the pyramid will receive less energy” is incorrect. Lower - level consumers (primary consumers) get energy from producers, and a decrease in secondary consumers (their predators) does not directly reduce their energy intake from producers.

Answer:

B. The higher levels in the pyramid will receive less energy. C. The lower levels in the pyramid will have less predation.
