Match each ecological pyramid concept on the left with its correct biological or structural feature on the right.
- Pyramid of EnergyAlways remains upright across all natural ecosystems because energy dissipates as heat at each successive trophic step.
- Aquatic Pyramid of BiomassFeatures an inverted structure where the producer level has a smaller standing crop than primary consumers due to rapid turnover.
- Parasitic Pyramid of NumbersExhibits an inverted shape starting from a single host supporting numerous individuals at progressively higher trophic levels.
- Ten Percent LawQuantifies the average proportion of energy converted into biomass and transferred to the next higher trophic level.
Answer
Pyramid of Energy matches with 'Always remains upright across all natural ecosystems because energy dissipates as heat at each successive trophic step.' Aquatic Pyramid of Biomass matches with 'Features an inverted structure where the producer level has a smaller standing crop than primary consumers due to rapid turnover.' Parasitic Pyramid of Numbers matches with 'Exhibits an inverted shape starting from a single host supporting numerous individuals at progressively higher trophic levels.' Ten Percent Law matches with 'Quantifies the average proportion of energy converted into biomass and transferred to the next higher trophic level.'
Each ecological concept correctly matches its underlying biological rule: the pyramid of energy is universally upright due to metabolic heat loss; the aquatic biomass pyramid can invert due to rapid producer turnover; parasitic numerical pyramids invert due to host-parasite population ratios; and the ten percent law defines ecological energy transfer efficiency.
