Question

which of the following statements about the energy pyramid is correct? select 2. as we go up in a biomass pyramid the amount of biomass decreases. as we go up the energy pyramid the amount of energy available in each trophic level decreases. as we go up in a biomass pyramid the amount of biomass increases.

Explanation:

In an energy pyramid, energy transfer from one trophic level to the next is inefficient. Only about 10 - 20% of the energy is passed on, so as we move up the trophic levels, the amount of available energy decreases. Biomass pyramids also typically show a decrease in biomass as we go up the levels because there is less energy available to support organisms at higher levels.

Answer:

• As we go up the energy pyramid the amount of energy available in each trophic level decreases.
• As we go up in a biomass pyramid the amount of biomass decreases.
