The pyramid of numbers can be inverted in certain ecosystems. Normally, in an ecological pyramid, the number of organisms decreases as you move from the base (producers) to the top (consumers). However, in certain cases, such as in large trees or parasitic ecosystems, the pyramid of numbers can be inverted, with more consumers than producers at a given level.
- The energy pyramid and biomass pyramid generally follow a normal shape, where each successive level has less energy or biomass than the level below it.
Thus, the correct answer is option (C), as the pyramid of numbers can be inverted in some ecosystems.
