Question

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, only about 10 - 20% of the energy is transferred from one trophic level to the next higher level. So, as we move up the energy pyramid, the amount of available energy in each trophic level decreases. In a biomass pyramid, biomass generally decreases as we go up the pyramid because higher - level consumers require more biomass from lower - level organisms to sustain themselves.

Answer:

As we go up the energy pyramid the amount of energy available in each trophic level decreases
