Observe the ecological pyramid given below, which includes specific quantitative data for each trophic level. Which of the following ecosystems and parameters does this pyramid most accurately represent?
Options
- APyramid of numbers in a grassland ecosystem
- BPyramid of energy in a freshwater lake ecosystem
- CPyramid of biomass in a terrestrial ecosystem
- DPyramid of biomass in a marine ecosystem
Correct answer
C. Pyramid of biomass in a terrestrial ecosystem
Step-by-step solution
Based on the given ecological pyramid, we can determine the parameter and the ecosystem by analyzing the units and the shape of the pyramid. 1. Parameter: The values are given in kg m ⁻² , which represents mass per unit area. This is the standard unit for measuring biomass. Therefore, it is a pyramid of biomass. Pyramids of numbers would just have counts (individuals), and pyramids of energy would have units of energy per area per time (e.g., J m ⁻² yr ⁻¹ or kcal m ⁻² yr ⁻¹ ). 2. Ecosystem: The pyramid is upright,
