In a tropical forest ecosystem, the energy pyramid has a typical shape, where energy decreases as it passes through the trophic levels. Suppose that, at the first trophic level, the total primary biomass produced annually by the producers is 1,000,000 kcal. At the second trophic level, the biomass of primary consumers is 300,000 kcal and, at the third level, the biomass of secondary consumers is 90,000 kcal. Based on these values and the understanding of how energy disperses in ecological pyramids, answer: (1) Explain what each trophic level represents in terms of organisms and energy transfer. (2) Discuss what the shape of the energy pyramid suggests about the ecosystem's energy efficiency and the implications for its ecological stability.
