Energy & Biomass Pyramids and transfer calculations

Which statement best describes the flow of energy as it passes through the organisms in the pyramid?

• energy flows through the organisms from bottom to top and increases at each level

• energy flows through the organisms from bottom to top and decreases at each level

• energy flows through the organisms from top to bottom and increases at each level

• energy flows through the organisms from top to bottom and decreases at each level
