Question

which of the following statements is not true of an ecological pyramid? energy is passed down a food chain or food web from the higher trophic levels to the lower tropic levels. ecological pyramids represent the decrease in energy, biomass, and numbers within an ecosystem. the ecological pyramid becomes smaller toward the top, where less energy is available. only 10% of energy is transferred between levels.

Explanation:

In an ecosystem, energy is passed UP a food - chain or food - web from lower trophic levels (like producers) to higher trophic levels (like consumers). Ecological pyramids show a decrease in energy, biomass, and numbers as we move up the pyramid, with less energy available at higher levels and typically only about 10% of energy transferred between levels.

Answer:

Energy is passed DOWN a food chain or food web from the higher trophic levels to the lower tropic levels.
