What illustrates the relative amount of living organic matter available at each trophic level in an ecosystem?

• A. Pyramids of Energy
• B. Pyramids of Numbers
• C. Pyramids of Biomass
• D. Food Chain

Answer: (C)

The correct answer, which refers to pyramids of biomass, illustrates the relative amount of living organic matter available at each trophic level in an ecosystem. Biomass is the total mass of living organisms in a particular area or habitat at a specific time, and it effectively conveys how much organic material is available for consumption by higher trophic levels. In a biomass pyramid, producers, such as plants, are typically at the base, representing the largest amount of biomass because they convert sunlight into energy through photosynthesis. As you move up through the trophic levels—herbivores and then carnivores—the biomass generally decreases due to energy losses at each level, primarily through heat and metabolic processes. This decrease reflects the limited amount of energy and organic matter that can be supported at higher trophic levels. Other options, while relevant to ecological relationships, do not specifically convey living organic matter. Pyramids of energy show the flow of energy through different trophic levels, emphasizing energy transfer rather than mass. Pyramids of numbers focus on the number of individual organisms at each trophic level without considering their mass. A food chain, while depicting the feeding relationships, does not directly represent the biomass at each level. Therefore, pyramids of biomass are
