What does each bar in the energy pyramid indicate?

Options

  1. AThe amount of energy present at each trophic level
  2. BThe amount of energy lost as heat at each step
  3. CThe total energy in the ecosystem
  4. DThe energy in a given time or annually per unit area

Correct answer

D. The energy in a given time or annually per unit area

Step-by-step solution

Pyramid of energy is always upright, can never be inverted, because when energy flows from a particular trophic level to the next trophic level, some energy is always lost as heat at each step. Each bar in the energy pyramid indicates the amount of energy present at each trophic level in a given time or annually per unit area .
