Question

what does a pyramid of energy illustrate in an ecosystem? random distribution of biomass decrease in biomass at higher trophic levels increase in biomass at higher trophic levels

Explanation:

A pyramid of energy shows the flow of energy through trophic levels. Energy decreases as it moves up trophic levels due to energy loss (e.g., through respiration). Biomass, which is related to energy (as organisms store energy in biomass), also generally decreases at higher trophic levels. A random distribution of biomass is incorrect as there is a pattern related to energy flow. An increase in biomass at higher trophic levels would go against the energy - transfer principles (since energy is lost, less energy is available to support a large biomass at higher levels).

Answer:

decrease in biomass at higher trophic levels
